An epic username for every pro Fortnite player.
Also means the act of poop in a man's butthole and asking him to poop into your mouth, so you'd be eating your own poop.
"Dude, I'm so mad that Poopmaster69 killed me!"
"Bro, some homelessguy asked to do the Poopmaster69 with me."
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
FRIEND A: "Did you just take a stealthie of me?"
FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"
