paint sprayer
A paint sprayer is when you're so full of beer and poop that you let one giant fart spray across someone's face like they’re getting hit by a brown paintball. It looks like they were dipped in turd sludge.
My cousin did the paint sprayer on my mom during Thanksgiving. She was crying and covered in diarrhea.
At the bar, Steve did the paint sprayer on his friend’s face. The guy looked like a smelly mud cake.
During the wedding, the best man did the paint sprayer on the groom. Everyone laughed so hard they puked.
