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.

Fuck knuckles

Fuck knuckles are when a teenage boy has been masterbating and constantly has jizz on his knuckles

I will never shake hands with my nephew Johnny because he constantly has fuck knuckles and seems to be always jacking off.
