A knuckle punch is when two fists collide in a totally ungay way. Its a proper word for what some GAYS call 'fist bump'.
Cause obviously bumping fists makes no sense.
KNUCKLE PUNCH ALL THE WAY.

Me- No. But I'm willing to do a knuckle punch with that sexy boy toy of yours.

Drew insulted me. So I gave him a "Two-Knuckle Punch" straight to the urethra.

the act of rubbing your knuckles up and down the palm of your hand until there right hot, then punch someone on there arm while holding your knuckles there for 3 seconds, they get punched and burnt at the same time!!!
