Someone who farts with a finger in their Ass. Knuckledusting isn't sexual in nature, it is much more closely related to fart sniffing or other Anal Olympic Events. There is a correlation between this activity and growing up in a trailer. This activity was almost certainly invented in the 70's when video games were all but non-existent and drugs were, well, the same as today

When a loved one or significant other won't help a bro out and he's forced to knuckle his own junk. Said bro shoots baby batter into his own hand and allows it to dry. The following morning punches the unwillingly participant from the night before creating an eruption of cum dust shooting from his knuckles.
