Tindermon Go is a game which is similar to Pokémon Go but it’s played with the Tinder app which you use collect the ugliest/fattest women or men by taking screen shots of them. Then you trade those pictures with your friends until the grossest fattest one wins!
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?"
