Knuckle one off

The same as Jerking off or the 5 Knuckle Shuffle

Did you hear Nic Pledged a Fraternity?

Yaa now he sleeps and showers with 50 guys in the same room. He said he has to go into the bathroom to Knuckle one off!

knuckle children orphanage

AKA foo-foo sock. Distiguished by its crinkled stuck-together fabric texture and usually found under the beds of adolescent males, it is the sock, or other fabric used by men to deposit the fruits of their masturbating escapades.

Johnny was horrified to walk in his room and find his knuckle children orphanage perched neatly on his pillow by his mother's cleaning efforts earlier that day. Unfortunately this was also the day that Sallie finally agreed to come home to his room after school.

Knuckle Dumpster

Someone who enjoys another person's fist being put into their body, especially used to describe homosexuals.

Dude #1: Portia De Rossi is redonkulously hot...
Dude #2: Nah, she is just Ellen's Knuckle dumpster.
Dude #1: That's a damn shame.

Knuckle graze

The unfortunate event when the toilet paper you are wiping with skims and slips off your ass, thus causing your knuckles to graze your half-wiped ass. A smell check of the offending knuckles will confirm or deny whether you need to cut off your hand.

This dollar store toilet paper offered me no ass traction; a knuckle graze occured, and now my knuckles look like shitty brown mountains.
