By the way, this is back when your like 5-6

Leonardo

You heard your dad and uncle Raph arguing again and you were trying to take a nap.

"Raph, you need to take responsibility. You can't just go running off like that." Leo scolded.

"You can't tell me to do! I do things MY WAY!" Raph shouted.

You came around the corner glaring at the two people and yelled, "SHUT THE FUCK UP!"

The two stopped arguing and looked at your direction, "Y/N! That's a bad word!" 

"I'm sweepy and you keeping me awake." You growled.

Leo checked the time and blinked realizing it was your nap time.

"Sorry baby, I'll tuck you in. But just don't say that ever again." He scolded picking you up to carry you back into your room to tuck you in. 

Except he knew that Raph would get a beating for saying bad language to a kid your age.

Raphael

You sat on the couch reading one of your dad's comics when Mikey arrived in the building.

"YEAH BOI! TIME TO TURN IT UP IN HERE!" Mikey shouted.

"Please be quiet." You mumbled.

Mikey didn't hear you and had opened a fresh box of pizza and grabbed a slice out to chow down. He didn't see another slice slipping out the box which the pizza fell on top of your head.

You slammed your book on the ground yelling at him, "YOU BITCH!"

Mikey was puzzled for a second until Raph came in to see what was going on. 

"Y/N, don't say that word again. Mikey, you going to get a beat down." 

"MEEP!" Mikey squeaked. 

Donatello

Donnie was in his lab making a new invention that would be useful when he and his brothers are out of control. You were sitting across the table reading a book he gave you to entertain yourself.

Au: What was childhood book plz comment. 

"Y/N, stay here and don't touch anything," Donnie said leaving the lab while you continue reading your book.

While you were reading something was steaming in the chemical glass as you called your daddy until the stuff exploded.

"OH SHIT!" You shouted.

Donnie ran into the lab and saw the messy room before looking over at you to check and make sure you weren't hurt. His worried side went away as he lectured you about never cursing like that again.

"You are one lucky charm." Donnie said.

Michaelangelo

Mikey and you were playing Mario games together, but once you were about to cross the finish line Bowser hitted you with a turtle shell.

"FUCK!" You cursed.

"Excuse me!" Leo scolded.

"Flower, no need to say that around. It's not nice." Your dad lectured before you both returned to your game. 

Splinter

You were in the dojo watching your brothers train until the brotherly rivalry between Leo and Raph began.

"Raph, it doesn't have to be like this all the time." Leo said.

"Here we go again." Mikey groaned.

"That's enough training, my sons." Splinter said. 

"I'm not going to be weakling to lame-O-nardo." Raph snarled.

"Asshole!" You shouted.

The room was silent as Splinter bent down at your height saying, "Never say that foul language again."

Shredder

He don't care because your already a badass baby after calling his allies "Fools".

Tiger Claw

You were sitting on the floor playing with your stuff toys while your father was out on patrol leaving you being watched over Bebop and Rocksteady. They were talking strange words that did not know or understand. 

When your father came back he saw you walking over to greet him with a smile.

"Daddy, what does bitch mean?" You asked innocently.

"Y/N, honey, never say that or ask me that again. But I will give you a treat right after I deal with the idiots." He said in a nice tone escorting you out of the room giving the two mutants a harsh punishment.

April

April was in the kitchen making dinner for you two, while you were watching television. On the tv, there were strange demons saying sexual jokes, demonic references, and strange symbols glitching the screen. As April went to get you she saw you watching "Hazbin Hotel" and gasped.

"Uh, Y/N, you shouldn't be watching that. It's not for kids." She said picking you up from the couch in her arms.

"But mommy, what's a shithead?" 

"Nothing you need to know about." 

Karai

Karai was training in the dojo with the other foot ninja's which were pretty weak and didn't stand a chance for a woman of culture. You were watching your mom train until she was taken down upon one of the soldiers making you angry.

"Eat my ass foot clan!" 

"Y/N! Language honey." 

"Sorry mommy." 

Casey

He doesn't know what do after he's been cursing around you lately and felt a shame do it.
