After three girls enter your dorm room and begin talking to you, this is what happens after fuckn knuckles enters your room:

Girls: hey(to fuck knuckles). do you live here too?
Fuck Knuckles: (does the double arm pump and screams in a loud gay voice, like a white guy trying to be lil john) YEAAAAAH!
Girls: (they promptly leave after giving a look of disgust to fuck knuckles)
Two guys who live in the dorm room: hey fuck knuckles, thanks a lot. (the guys begin to bumrush fuck knuckles and beat the shit outta him for being such a douche)
