MacDarby's Sign - Poop on your head. Happens when someone throws a used glove

Poop on your head. Happens when someone throws a used glove at you after looking at your butt.

I got hit with a glove. Poop is now on my face. I'm gonna be the joke of the year.

After the exam, a glove full of poop hit me. Now my face looks like a smelly pancake.

He flung a glove at me. Poop splattered on my face. I'm gonna be the talk of the town.
