When someone shoves one of their fingers up their arsehole, then pulls it out to see if shit gets on their finger or not in order to decide something one way or another. A game of chance, of sorts, like flipping a quarter to decide or determine something. If shit gets on your finger the answer is "No", but if you pull it out clean the answer is "Yes".
Well, I don't know if I should go to the show tonight or not. I guess I'll have to decide using the Fecal Finger of Fate.

When one of your co-workers at your firm takes the communal Boston Globe newspaper from the firm's library with him to the mens room, then proceeds to take a massive, stench-ridden, vomit-inducing dump, and exits the stall with the Globe under his arm and fails to wash his poo-ridden hands.
Dude, do not touch the Globe in the library today. Sid fecal fingered it. He read it while shitting and then never washed his hands after wiping his massive ass.
