used to refer to a younger modern kid who is, basically, a hippy wannabe. The individual dresses in the typical "hippy uniform" of tie-dye, Birks, shredded jeans, and Phish tee (or the like) and is often too baked to tell you "up" from "down". This individual is basically has no concept of what the original, hippy culture was about and only associates with hippydom because of his love of wake-n-bake.
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?"
