Yes, guys usually take advantage of girls, but this is the opposite. Also, relatable to situations when that certain friend doesn't want to admit to the previous night's blunder.
Friend 1: hey suit, you sleep with that girl last night?
Friend 2: not exactly sure.
Friend 1: ah, we got ourselves a snatchitory rapecase.
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?"
