Stink Finger Bingo, is a game played by a gathering of people. Gender does not apply. Players are blindfolded and proceed by sticking their finger in a random ass. Next they must guess which ass they had penetrated with their finger through smell. If they guess wrong the process is repeated until a correct answer is given.

The act of inserting your own index finger into your ass crack to achieve a high level of ass stink then sneaking up behind your best friend and rubbing your finger under his nose to transfer your ass stink onto his upper lip.
After soccer practice, Bobby came up behind me and gave me the fucking nastiest Baron Von Stink Finger ever. I just about threw up.

This is a derogatory term for the sexual act of being fingered. This is the insertion of fingers or ties into a sexual cavity, usually for pleasure. It referees to either the girls vagina smelling rather rude ie: fishy (like opening a tin of sea product cat food) or dirty in some sour way or the guy /girls hands having been grungy to start with. Really not a good thing. May also have references to anal or butt fingering. Which leaves the extremity smelling a little nasty afterwards. All round an unpleasant rather obnoxious experience. Can be easy remedies with intense hygiene protocols. Should rather be avoided where possible.
Stink finger. Stink fingering, stink fingered.
