A mental Disorder that is caused directly from the consumption of Beer(or any other alcoholic beverages). The characteristics of this affliction are very easy to recognize, ie. the transformation a generally nice and hospitible person to a blubbering lunatic who's every emotional scar and guitly conscience has taken control of them.
"That chicks O.K. when she is sober, but after a few drinks she becomes completely beer polar"

When a person has a completely different personality after drinking a few beers. Most times a beerpolar person goes from opposite ends of the personality spectrum. Such as being very shy and quiet to being loud and obnoxious.
Kendra was so friendly last night, it was almost creepy. She is usually a mega bitch. That's because she was drinking last night, the girl is totally beerpolar.
