After a make-out session and cuddle nap the boys wandered back to the Christmas common room. Both had changed into their regular clothes again. They were hungry and there had been so much food left they knew exactly what they were going to eat.
The food was still there, a little cold, but still good. The boys filled up their plates and ate until they could physically eat no more. Karkat looked at everything still left on the buffet line and saw a punch bowl half-filled with some unfamiliar liquid. "What's this?"
Dave walked over, "Oh, I think that's Rose's eggnog, her mother's recipe."
"What's it taste like?"
"Dunno, Bro always hogged the eggnog during Christmas. I've never had any."
"Let's try it."
The boys filled two glasses and each took a sip. It was good, really good. They smiled at each other and soon finished off what was left in the bowl.
"That was really good. No wonder humans drink it."
"Yeah, I've been missing out."
They giggled at each other, finding everything incredibly humorous. The Mayor soon approached them, clearly wondering what all of the mirth was about. Dave was the first to notice him.
"OH MY GAWD MAYOR! WANNA PLAY?!" Why was he shouting? He didn't know and didn't care, he grabbed the Mayor and decided that he was going to give him a piggy back ride. He was laughing the entire time, yet did not have the self-awareness to question why. The Mayor thought everything was a game and just went along for the ride.
Karkat stood up with Dave swaying a little "What're we gonna do Davey?"
"I dunno, jusht c'mon." He took Karkat's hand and they ran, where to? Neither knew, or cared. They made their way down the way stumbling and cackling the entire way. Eventually, coming to another common room, yet they were completely unaware that the room was already occupied.
"C'mon." Dave motioned for the Mayor to step down and grabbed his hand, while grabbing Karkat's with the other. And they were spinning. The two people having a discussion, whom the boys had interrupted just stared dumbfounded for a moment before laughing hysterically. The boys were too filled with their own giggles to notice; however the spinning soon became too much and they fell over, laughing uncontrollably. "Oh man, I'm gonna be shick." Said Dave.
"Me too."
Vriska noticed the tone in their voices and recognized it from somewhere before. "Do you two seriously have that problem too? Really Karkat? I expected better from you at least. And Dave, you saw how it affected your sister."
"What're you talking about?" Dave slurred. "I haven't done anyshing." Not noticing his own slurred speech.
Just then Rose rushed in. "Dave did you-?" She didn't even have to finish her question, the evidence on the floor. She couldn't help but chuckle. Vriska saw her and inquired.
"Is this a common human issue?"
"I don't think Dave realized that some eggnog has alcohol in it. It appears they drank entirely too much. Would you help me get them into bed?"
Vriska reluctantly nodded, Terezi was laughing too hard to be of use to anyone, but still managed to distract the Mayor so the other two could help the boys. They coaxed the boys back to their room and into bed. Rose helped them both the next day with their hangovers.
