Fuck Knuckle

A dickhead who likes to invade everyones privacy and will happily eat cock whenever is possible. He/She talks too much and needs to be sent to South Africa to drop him/herself on his/her own head. They talk out their ass most of the time.

tainted knuckles

Tainted knuckles occur when you reach between your legs to wipe your ass after a shit and your knuckles touch the vile soup in the toilet bowl or,heaven forbid,the turd itself.

Damn! I'm going to have to wash my hand.I got tainted knuckles.

bloody knuckle

When 2 girls are each on their period and scissor each other.

Jen and Pam were both on the rag, and horned up for eachother, so they got into scissor position and bumped the bloody knuckle.
