Nut Rippler 

When you fart on a bus with your legs closed and the gas has no where to go except up either your left nut or right nut. It feels like you shit yourself. But when you stand up the gas releases silently and your nut falls back into place.

Man I was sitting beside this SFU and I had a nut rippler. Didn't want to move or it would smell.
