Beercula (pronounced bir-kool-ah) is a personification of the fictitious blood sucking vampire but, with a sort of birth defect. Instead of being damned (counter of baptism) with blood, it so happened that the Beercula fell into a cauldron of beer - which was being brewed to lure his first prey. Hence the Beercula now sinks his fangs into kegs or kenny rogers instead of voluptuous virgins' jugulars.
The Beercula is having his mid-afternoon froth-i-cure.
Beerquilibrium is the state at which a person is able to drink several beers with relatively little change in her or his level of intoxication.
So I had that Fourloko at the beginning of the night, ate some pizza, and then I switched to beer like an hour ago and since then I've pretty much been at beerquilibrium.
