After downing five beers. I decided to make Yaomomo shit herself. Yes, I am aware that I am likely drunk while writing this. Maybe once I sober up I'll delete this monstrosity.
"Hey guys, me and Mineta bought us some sandwiches!" Kaminari called out to the residents of Heights Alliance. "We know that you all ate breakfast already so if you don't want it it's fine you can just pack it for lunch."
"No, it's okay Kaminari-kun." Said the Iida the class president.
"Alright then!" Kaminari smiled as he begun handing out the sandwiches to his classmates.
"Mina this is yours."
"Thanks."
"Hagakure."
"Thank you."
"And Yaomomo."
"I appreciate it, Kaminari-san." Momo smiled as she accepted the offered food.
"Let's see who's this one- Wait, that can't be right." Kaminari whispered, almost worriedly.
"Umm, Momo?" He turned towards the pony-tailed girl only to see that she's already began to eat it.
Kaminari's eyes widened in horror, his mouth dropping so slightly. Momo noticed his reaction and turned towards him. "Kaminari-san, is something wrong?" She asked.
The lightning user immadiately regained his composure. "Oh uhmm, nothing Yaomomo."
He then began to walk away.
Momo looked at him confusedly before continuing to take a bite out of the sandwich.
(...)
"WHAT?!" Screamed Mineta.
"I- I gave her the sandwich meant for..." Kaminari looked down in shame, clearly regretting his actions.
"And you didn't try to stop her?!"
Kaminari put his hands up. "I know, alright! I should've stopped her but I panicked."
Mineta was pacing the room, sweating profusely before stopping and sitting down. He then buried his face in his hands.
"F-fuck man, what do we do?" Kaminari asked, fearing for his life.
"I don't know, maybe give her an entire bulk of toilet paper and pray that she'll forgive us." Mineta suggested.
"Or maybe we could just blame natural causes. Like, you know? Salmonella or a stomach bug?"
"Idiot, They won't buy that! And this is all your fault! None of this would've happened had you'd stopped her from eating that sandwich!"
"Me?! This was all your idea!"
"It doesn't change the fact that you still agreed to it!"
For the next several minutes the two would continue to try and place the blame on each other, eventually they reluctantly agreed that they were both at fault.
"Let's just get to class. Aizawa sensei might give us something worse than explosive diarrhea."
"You know we might actually get arrested for this right?"
"Shut up. man. Besides, maybe the doses weren't enough to give her side effects."
It was, in fact, enough to give her side effects.

Momo was busy taking notes on foreign quirk laws when she felt it. A slight rumbling sensation in her abdomen.
She didn't think much of it at first.
Ten minutes later the sensation has developed into an actual stomachache, the urge to go to the bathroom came not long after.
She tried so so hard to ignore it, she couldn't go to the bathroom now, not when Aizawa sensei was still discussing the importance of knowing foreign laws on heroes. She focused her attention at Aizawa sensei's lecture hoping, praying it would subside.
It didn't.
By now the cramps were so severe that she could barely focus on the lecture anymore, cold sweat started to form on her face. And to make it worse her classmates were starting to notice her.
"Yaomomo, are you ok." Ochako asked with genuine concern.
"Yes." She answered as if there was a gun pointed at her head.
"Um, are you sure?"
Momo turned and smiled at the gravity user, all while gripping her pen with such force that Ochako swore she heard a crack. "I can assure you, Ochako san. I am quite fine." She assured her through gritted teeth.
Ochako wanted to ask a few more questions like, Why are you sweating? Why are you grinding your teeth when you talk? Why do you look like you're about to poop yourself? But her instincts told her that she would receive a fist to her face if she asked the last question. So instead, she just gave a shy nod and went back to listening on the lecture.
Three minutes had passed and Momo couldn't take it anymore. To hell with the lecture! She'll surely soil herself if she continued this pointless endeavor.
She raised her hand. "Sensei, I need to go to the bathroom."
Aizawa narrowed his eyes at her. "There's only five minutes left in my class, can you really not wait?"
Five minutes more and I will surely soil myself Was what she wanted to say. ''No sensei, I don't think I could."
"Well then go right ahead."
Momo then stood up and calmly walked towards the exit, once outside she bolted towards the nearest restroom.
(...)
Everybody was staring at the door, with the same confused expression on their faces.
"Alright, I know most of you have already noticed something odd so I'll cut to the chase. What is wrong with Yaoyorozu?"
Kaminari and Mineta gulped, sharing nervous looks with each other.
"She looked like she was in pain." Said Mina.
"Yeah, and she looked kind of pale." Added Kirishima.
"Not to mention sweating." Hagakure also added.
(...)
"Hey momo-"
"Wassup Yaomomo-"
"Hey! No running in the-"
She ran ignoring the voices of the 1B students greeting her or the voice of Sekijiro sensei telling her that she couldn't run in the halls.
No, she didn't have time for any of that. Especially when the gates to hell were about to open.
She reached the women's restroom and yanked the door open with such force that it nearly broke its hinges.
"Oh heya, Yaomomo." A green haired girl whom she recognized as Setsuna Tokage from 1B greeted her. But Momo simply walked past her and secured the first unoccupied stall. "Huh, rude."
Momo was practically shaking as she struggled to undo her skirt. She could feel her self control declining that she even considered ripping her skirt off altogether.
Finally after a few seconds that felt like an eternity, she finally undid her skirt, pulled it down along with her underwear, and sat on the cold seat of the toilet.
What followed was a series of loud and disgusting explosions of watery stool, her anus burned as she emptied her rectum.
Groaning in both pain and relief, she placed her hand on her abdomen. The cramps still hasn't subsided but the relief in releasing a burden was beyond words.
"Oh my, that didn't sound good. Are you ok?"
Oh dear, how could she forget that she was still here?! Having a minor panic attack for a moment, she recomposes herself and answered. "I'm fine Tokage san. My stomach just seems to hate me right now."
"Yeah no shit, that sounded like an entire day's worth of meal dumped on the toilet. Literally." Tokage laughs, as Momo buried herself in her hands, wondering what led her to thid predicament.
"You know, I always assumed you shit a lot given the nature of your quirk."
Momo's eye twitched. "I-Is that so?"
"Yeah." The 1B girl then proceeded to explain to her about how she deduced that in order for her quirk to work, she would need to have an accelerated metabolism. Which isn't technically untrue. Momo was genuinely impressed with her intelligence.
But then Tokage began talking about things that had nothing to do with the previous subject, from her friends antics to how Aizawa sensei apparently doesn't sleep.
Momo sits there, skirt and underwear down on the toilet with her stomach killing her listening to this girl talking gibberish. She wonders how can she end this conversation without sounding aggressive or rude.
Or maybe she could wait this out. This was going to take some time anyway and 1B's lunch break should be over soon given that they have different schedules.
She looks down for a moment and her eyes widened. And then comes the realization, it turns out she did not escape this battle unscathed. The disgusting greenish yellow chunks stained on her underwear was unmistakable.
For some reason it reminded her of the sports festival, where she barely lasted a minute against Fumikage. And now she barely won against her own bowel movements.
Tears began to well up in her eyes as she desperately wipes them off with her sleeves. She is absolutely not going to have a mental breakdown here! Especially not when-
...Wait.
Of course! How could she forget? Damn her digestive tract for even affecting her logic.
She grabbed her wallet from her skirt. Thankfully it wasn't stained. "Umm, Tokage san?"
"Hmm, what is it?"
"I-I need you to do me a favour..." Embarassement was clear on her voice alone.
"Anything for my diarrhea strickened 1A friend!"
Momo slid about 17,000 yen from the stall door. "I-I need you to go to our dorms and fetch me a new skirt and underwear... And a trash bag."
Tokage stared at the cash for a moment. "... That bad, huh?"
"Yes..." Momo confirmed reluctantly. "I can't really use my quirk in my current condition. So could you..."
'First of all, that's a lot of money. Second of all, its not like I'd be allowed into your dorm anyway."
"Ah, of course... How could I forget..." Momo's began to look depressed again.
"But I can lend you my PE uniform. We already finished our physical training an hour ago anyway.""
Momo perked up. "Really? But wait, I can't wear it during class, that would be a direct violation of the dress code."
"Dude, you're literally shitting your guts out. Just get a slip from recovery girl and you'll have the rest of the day off."
"I'm really really thankful for you, Tokage san!"
"Heh, its nothing really... Actually can I still have the money? I spend most of my allowance yesterday."
Most of class 1A were having lunch at the cafeteria. Most of them were eating at the same table as well.
"Hey, any news on Yaomomo?"
"I saw her exiting the infirmary. I didn't understand why she was in PE uniform and carrying a trash bag though."
The entire table went silent on Kirishima's answer. Kaminari and Mineta choked on their foods and both excused themselves.
"What?" Asked the redhead in confusion.
"It is... Understandable." Said Iida.
"Yeah, it happens." Added Mina.
"Shit, man." Muttered Mineta.
"What do we do?" Asked a panic Kaminari.
"I-I don't even know anymore." Said Mineta in a resigned voice.
"There you are."
The duo turned to see their homeroom teacher approach them.
"Care to explain what this is?" The teacher held up a piece of paper.
"Umm, with all due respect, sensei. But we don't know what that is."
A glare from the Eraser hero silenced them. "This is a result of Yaoyorozu's stool test done by Recovery girl. As you can see, it says here that there are high amounts of senna glycoside in her stool. If you aren't aware, is the chemical used in laxatives."
"Tell me Kaminari, what happens when you take too much laxatives?"
The boy tries to play dumb. "I don't know, sir."
Aizawa didn't buy it, but still went along. "You don't know? If in that case I'll educate you. Taking too much sennoside or laxatives can cause abdominal pain and diarrhea. Symptoms that Yaoyorozu displayed earlier."
"You gave your classmates those sandwiches earlier right? Since your other classmates didn't suffer the same fate as Yaoyorozu, it means you were saving it for someone else. Now tell me, who was the original target?"
"It was Bakugou." Mineta finally confessed. "We wanted to get back on him for humiliating us."
Aizawa narrowed his eyes at him, before nodding. "I believe you. But both of you will be undergoing counseling with Hound dog. This vengeful attitude is unbecoming of a hero, and now one of your own classmates suffered because of it."
The end, I think imma throw up.
