A phrase used to describe the act of publicly announcing personal and/or private information in an inappropriate setting.
A friend of mine had anal with a fat chick, and then by way of flapping the paper asshole let everyone know about it at the bowling alley. He received a lot of awkward stares.....
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.
