A term used for a human who is evidence of devolution - humans evolving back into apes and other primates.

This man often dribbles in public places; cannot drink a hot beverage without spilling it on himself, the floor or someone else; may walk into objects like lampposts and bushes; may ask questions repeatedly such as "how are you doing?", or "hows your computer software going?" and has an interwoven, messy beard that houses flees, mites, pieces of pork and dribble.

It's safe to say that the knuckle draggers of this world are a frightening breed, who you should avoid if at all possible.

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!
