A highly contagious disease spread only among men. It causes the victim to exhibit large, unquantifiable amounts of asshole-ness and stupidity. It inhibits common sense and causes a depletion of brain power usually resulting in dumping, slapping, and being called names by the opposite sex. There is no known cure.
Your man has a mad case of the cooties, you should dump him.
This dude's a complete asshole, he must have cooties.
