Fudge knuckle

When you put your finger up a butt during sex/foreplay, and you go a little too deep, resulting in a bit of poo on your knuckle.

Dude1: how'd it go with that chick last night?
Dude2: not bad. She wanted me to finger blast her butthole, so I did, but I got a little over zealous and ended up with a fudge knuckle.
Dude1: oh man. that's fucked up!
Dude2: yeah, but she ended up riding me all night so....

knuckle dragger

Adj. This term is used to describe a snowboarder who is insane at what he or she does. Calling someone a knuckle dragger is a compliment, do not take offense to it. It is a great term because skiers can never be knuckle draggers, more or less because they suck huge dick. Knuckle draggers are often seen in the terrain parks of your Local Mountain or ski resort. Don’t fear them, they are just 10 times better at snowboarding then you will ever be. CAUTION: If you ski and you cut off a knuckle dragger it will certainly lead to your death. However this should never happen because you do not belong in the terrain park!...keep kids on shred!

Skier 1: That kid just did a 720 tail grab clearing a 50ft gap!
Skier 2: He is a knuckle dragger man don't mess with him.
Skier 1: Damn i bet he gets laid a lot!
