Common name for Bovine Spongiform Encephalopathy (BSE), a cattle disease that causes the brain to waste away. It takes about 4-7 years for cattle to show symptoms of the disease after being exposed to it, but once symptoms become visible the cattle die within weeks. One way this disease is spread is by feeding the meat from infected cattle to other cattle (meat from infected sheep may also cause the disease). OTHER ANIMALS...IE, FISH CAN NOT GET THIS DISEASE!!!!!!!!!!!!!!!!!!!!

1. Angry cow. (Possibly see your mom).

2. BSE; Rots the brains of cows and jerks who eat cow brains. (Possibly see Indiana Jones and the Temple of Doom. Or was that monkey brains? Whatever, it's feking weird anyway).

3. Giant lesbian who thinks she's hot. When you yank on her quadruple D breasts, she does not notice it because they're dragging on the floor already. But for some reason, skinny hot lesbians find her attractive, but she is mad because men still exist, and her vagina cannot be found by said skinny hot lesbian. If you are a man, she will not appreciate you existing.
Your mom might be mad cow type one, but she can't be mad cow type two unless your dad had sex with a straight woman who carried you to term. Unless you are a girl, then your mom may be touching you when you're asleep, on the boobies, perhaps.

A diesese which is carried through the air and turns cattles brain to the same mush your grandmother eats at her old folks home. Remember the best way to combat the diesese is to wipe front to back at all times.
