Disclaimer- I do not own.

A/N- I'm sorry but I saw one of kendrawcandraw's comics on Tumblr where she has a theory that Blaine just can't swear. So here's a fic!

Kurt first began to realise how Blaine spoke when he joined McKinley. He'd just thought that if you dormed at Dalton they injected you with dapper so you were proper 24/7. But honestly, this was a low-budget public high school and nobody is eloquent. They probably don't even know what that word means.

Kurt was sitting with Blaine, Tina, Rachel, Mercedes, Santana and Brittany when he first heard it.

Blaine picked up his coffee when Brittany accidentally elbowed him, causing him to spill coffee on his jacket.

"Frog!" Blaine muttered as he quickly dabbed at the hot liquid.

"Excuse me?" Kurt said, not sure if he heard Blaine right.

"Frog," Blaine said louder and with a confused look from Kurt, the conversation was dropped.

A few weeks after that incident they had their first time. It was lovely and romantic and special. But one thing kept coming back to him.

"...K-Kurt...ohh, OH!" Blaine moaned while Kurt stroked him through his pants.

"Jiminy Cricket..."

Kurt's eyes flew open and looked up at his boyfriend to check if he was just imagining things.

But of course, Blaine did say it and Kurt was reassured of that fact later into the night, when Blaine was at a high.

Finn was getting to Blaine. Kurt could see that. His stepbrother was being blatantly rude and horrid to his amazing boyfriend, not even letting him speak in glee club.

They were walking to Kurt's locker after practise and Blaine was grumbling about Finn to him.

"I mean for the love of bow ties can't I just say something?!" Blaine ranted.

Kurt raised an eyebrow but let him continue his rant. But that exclamation was noted.

Kurt was over at Blaine's house and was currently seated at the kitchen island while Blaine had his head stuck in the fridge.

"Botheration! There is no pie left!" Blaine whined and that's when Kurt snapped.

"You never swear!"

Blaine looked up at him with wide eyes and a confused face.

"S'cuse me?" Blaine said.

"You. Never. Ever. Swear! Can you?" Kurt asked.

"It's not a nice thing to do," Blaine tried to protest.

"You weren't complaining last night when I was saying 'Fuck' like it was the only word I knew," Kurt muttered and Blaine's cheeks darkened.

"There are always exceptions." he relented.

"But not for you! With your Jiminy Cricket's and frogs and for the love of bow ties! It's like your from the 19th century!" Kurt exclaimed.

"I-I don't know. I'll try," Blaine said, "Fuu...F-fuuu...Fuuudge."

"Blaine, honey. I think you have a problem," Kurt said nicely while he pulled out his phone, pressing Puck's number and putting it on speaker.

"Puckosaurus speaking, who is it?"

"Puck, it's Kurt. Blaine needs help. Please say every swear word you know repeatedly until I tell you to stop." Kurt said and Blaine hung his head down, ashamed.

"Ok, bro. Shit," Puck started.

They were still on the first round half an hour later.

A/N- I'm so sorry, I don't even know what that was but I'm very tired and haven't had a proper sleep in days so this is the outcome. Goodbye and review if you want.
