The rules are simple (as they need to be for drunkards as yourself):

Get pounced, drink.
Get spit on, drink.
Get boomed, drink.
Get charged, drink.
Get jocked, drink.
Get pulled, drink.
Get incapped, drink.
Die, take 2.

Only rule for infected is the "ohshit" boomer (thanks Russian). If you are infected & happen to get the boomer, you drink just because you got the fatty.
