The hot air balloon is when you fart in someone’s mouth, they swallow said fart, and then due to the laws of physics that hot air rises, one must do a handstand in order for the fart that has been digested to make an expedited movement to the recipients colon. At this point it may be ejected forcefully onto or into the other partner, or into the room.

The phenomena in which a man is sitting on a typically non porous surface area such as a wooden chair, and unleashes a fart that instead of sliding out of the back, up the crack, it sneaks up the front and tickles the testes/ball sack. In some cases can elevate the sack if wearing loose clothing.
