Putting a thumb in your anus to stimulate the vasovagal response to the point to slow your heart rate down to prevent shock or death from bleeding, can also be used for pleasure also.

Classmate: "Has anyone talked to her about the break up?"
Me: "Na. She's been thumb fucking her phone all day and won't talk to anyone."

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.
