Fuck Knuckles 

one who seems to fuck things up everywhere he goes

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)

Fuck knuckles 

Fuck knuckles are when a teenage boy has been masterbating and constantly has jizz on his knuckles

I will never shake hands with my nephew Johnny because he constantly has fuck knuckles and seems to be always jacking off.

mexican fuck knuckles 

When a large mexican man shoves his knuckles violently in the (mexican) females vagina, and spins his hand around counter clock wise, as if he were opening a jar of jelly. Then he takes his other hand, and opens up more space to then stick his penis in and masturbate. with both hands.

what the fuck is with these crazy boarder hoppers doing all these mexican fuck knuckles in gas stations.
