A distasteful member of society that has the unusual urge to shove macaroons up his asshole and eat them after they are eject ejected by the sphincter out of the asshole.
I was friends with this guy until I found out he had been a shmuckaroon since we were twelve and I didn't even know until I bought him a box of macaroons
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?"
