look up any word, like dirty sanchez:
 
1.
The crease in jeans or pants at the crotch where the zipper is that pops up when sitting, or when big enough, when standing. Always looks like an erection, but is just the denim or cloth that folds up when in a seated fashion.
Hey don't sit down or everyone will see your botchka. Whoa, you got a double botchka!

A game in which one places two numbered dice in one's mouth, swallows them with ipecac, and then vomits the dice. One then retrieves the corresponding number of cards from another player's back pocket. Any further rules are improvised.
The boys played Botchka down in the basement, and now the floor is saturated with vomit.
