The process of cupping your hand against your ass while emiting flatulence and then holding the gas in your hand while bring it to another person's face and letting them inhale. Inhalee may or may not enjoy.

George gave Chris a kuppenheimer yesterday. It smelt real bad.

Uppenheimer 

When a person or people with names starting with Up ( eg: Upasana, Upam, Upjeet) gets angry at you and is about to explode, obliterating you in the process.

Please don't drop an Uppenheimer on me. Feel the wrath of The Uppenheimer.
