What is Slipshout?
1.
It's what you have to do when you're trying to pass someone, and they block your way, either out of mental thickness, sense of entitlement, they're preoccupied or out of inconsideration. It's a huge sign of disrespect when you have to yell: "Excuse me," really loud just to get someone to stop staring at you and move out of your way. This is the SlipShout.
"Everytime I see that guy, I have to do a SlipShout."
