fecal fingered

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.
