Caseoff 

A contest between 2 or more participants to shotgun 12 beer fastest. Vomiting is permitted and expected so a suitable puke bucket is placed in the middle of the contestants.

The Champ and Big Daddy were arguing about who could drink a dozen beer the fastest. The only way to settle it was to have a caseoff right there.
