moonpigging 

Moonpigging is the act of going out at night with the intention of getting drunk and then making out with as many hideously ugly women as possible: such a woman is known as a moonpig.

Moonpigging is sometimes the basis for a competition between teenage boys and/or young men - the formation of moonpigging societies is not uncommon.
