Hershey Thumb

When your boss or co-worker sits around with their thumb up their ass all day doing nothing. Once it's time to go home they remove their thumb which the tip is brown, coated in doo doo, resembling a Hershey Kiss. Sometimes they have poor hygiene and toilet paper is stuck to it as well representing the niggly wiggly completing the appearance. In many cases of frequent laziness and constantly doing nothing the thumb will be permanently stained from the feces.

Hey Joseph you got another piece of candy I see you have one already? Nah Levi I been hiding in the back doing nothing as usual. My fingers are just stained and have the ol' Hershey Thumb now.
