When someone jokingly pulls your pants down, it is called "pantsing". To use the word in a sentence, "Brian was pantsed by Eddie. Everyone laughed at Brian's pantsing!"
Some people say its when you pull down your pants and show your butt

Wear really loose fitting pants with no belt and then, if you're a guy, tell your friends that you have on tighty whties. In my experience, the temptation to pants a guy is always that much greater if people know that the guy has on tighty whities and therefore his humiliation will be more extreme.
