the act of urinating at the bar vs. making the trip to the bathroom
Minding my own business at a sports bar in Chicago when I feel something against my feet and legs. Turns out the guy next to me was Barpissin so he wouldn't miss any of the game.
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.
