Verb, as much as annoying, vain scene kids take many photos of themselves anyway and believe that they are incredible photographers for some reason. They frequently do this... 'pose' where they snarl, lifting one lip up towards the nose and usually tilt their head.
It's very stupid, but hilarious that they think they're cool for doing this face.
Scrolling across Facebook, oh look it's "Jessica OMG Bieber" (notice that the scene kid has a false surname and middle name.) Oh, what an annoying profile picture, she's pulling a face, this is know as The Scene Kid Face.
The Scene Kid Face is a COCK IN ASS
