Post Up
To post up is to lean against a wall, table, refrigerator, countertop, and in some extreme cases holding on to the ceiling, or any other convenient surface so that you do not fall down after consuming massive amounts of alcohol. Not only does this allow for a misconception of exactly how drunk you are, but it also makes a viable applicant for the next game of beer pong.
Dude 1: "There ya go Verser, post up. Don't let em' know how drunk you are."
Dude 2: "Is Verser posted up on the ceiling? Jesus H. Christ he has got swag!"
Dude 3: "I got Verser next beer pong game!"
Dude 2: "Is Verser posted up on the ceiling? Jesus H. Christ he has got swag!"
Dude 3: "I got Verser next beer pong game!"
