sad grandpa 

Sad grandpa is to be said when anyone is getting ready to change. It is a sign to all other people in the room that clothes are getting ready to fly, and to close all doors and to look away if you don't want to see "the goods."

Hey guys I gotta get ready for practice... sad grandpa.

Alright man, I'll get the door on the way out.
