v. - To intentionally collect shit (
feces, including dingleberries, butt sweat, etc.) onto one's
finger (commonly the middle
finger, being the longest) and, upon exiting the bathroom or other relief area, then seek out a particularly intolerant, insufferable, jerky, arrogant,
drunk, or otherwise undesirable person (see also: shithead) and proceed to approach them from behind (or sneak up on them), grab them by the face, and stick the shit-greased
finger past their lips and into their gums (but not beyond, so as not to get bitten).
This act is one of extreme boldness, bravery & conviction, and should be reserved only for the worst offenders and/or situations where one can escape quickly and with ease.

Ned:
Jesus, that guy is an
asshole.
Larry: He might just be drunk.
Ned: No, he's still a tremendous
asshole, he's been like that the whole concert. You should've heard him when we came in, too.
Larry: Is it bothering you that much? Then fuck it, give him a shitfinger, right in the gums. I've got your back.
Ned: Yeah. Man, I never do that, but that fucking guy deserves it. Hold my beer, I'm going to hit the port-a-potty and will be right back.
