proximity mine 

Pooping into the tank of a toilet, and taking the float out. This will make poopy water overflow from the toilet tank. The pure genious of this action is that most people almost always leave the bathroom while the tank is still filling.

"I went to that frat house last night and planted a proximity mine, by taking the float out and pooping in the tank of one of their toilets."
