Knucklebuster

One who likes to work on his own shit yo. One who likes to have split knuckles with blood and greese all over his/her hands. Like to say take a muffler off yo with a hammer and chisel and a cut off saw at 3:00 in the morning while the neighbors sleep. Knucklebusta yo

Like when your taking off a rusty U-clamp bolt from a muffler with a ratchet and you apply full force and the bolt snaps off forcing your hand full force into a jagged rusty piece of metal on the frame or some shit.

knucklebutt

A girl who is so skinny, most likely from anorexia, that when she wears a bikini you can see the bones of her pelvis move around in her ass when she walks because she has almost no butt cheeks.

"Danm! Someone tell that knucklebutt bitch to get some meat on her!"

knuckleduster

Someone who farts with a finger in their Ass. Knuckledusting isn't sexual in nature, it is much more closely related to fart sniffing or other Anal Olympic Events. There is a correlation between this activity and growing up in a trailer. This activity was almost certainly invented in the 70's when video games were all but non-existent and drugs were, well, the same as today
