Yugoslavian Sea Mine

The process of a man inserting a bike/ball pump into his urethra and pumping it up causing his bladder to expand and then inevitably explode inside of him. Usually done with a hand pump, but an electrical equivalent can be used for the daring.

Guy 1: Dude, why do you have that pump? You don't even own a bike.
Guy 2: Oh, I'm planning to enjoy a Yugoslavian Sea Mine this evening...
