(n) Anything that is discernably not beer. Derived from the Beer/Not-Beer dichotomy, which dictates that anything and everything in existence (and non-existence) can be placed in one of the two aforementioned categories.

Note: Recently, "Not-Beer" has been colloquialized (adj), meaning: stupid, lame, unworthy of praise, worthy of scorn, etc. Due to the recent colloquialization of "Not-Beer," its positive form, "Beer," has only naturally been adopted as an antonym (adj), meaning: cool, awesome, unworthy of derision, worthy of commendation, etc.
