Jaw Hanger (noun): When your jaw takes a leisurely stroll south, showcasing a face stuck in a constant state of confusion. Side effects may include driving that mimics a turtle's commute – slow, meandering, and with the occasional confused detour.
This damnJawHanger is going damn near 20 miles under the speed limit.
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?"
