The sneaky douche bag who does douchy things in secret, most often stealing perfectly good food from your fridge while you're sleeping, and throwing straight in the trash.
Yo dog, this morning I woke up and my bucket of KFC was in the trash. I think I got visited by the douche fairy!
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?"
