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.
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!!!

When you pass up a night of fun with friends and family to sit around alone at your place with porn and masturbate over and over again. During this time you wonder periodically between sessions if you made the write choice. This will often start to seem like work, but since you already passed on the fun you might as well do a good job of punching the knuckle clock...
The whole place stank of jizz and loneliness. A tear ran softly down my cheek as i continued punching the knuckle clock..
