Mickey D's 

A slang term for McDonald's. McDonalds was created by Richard and Maurice 'Mac' McDonald in San Bernardino, CA in 1948. They were later bought out by a man named Ray Kroc, who turned McDonald's into its current incarnation. The McDonald brothers renamed their restaraunt 'The Big M', and Ray Kroc opened a McDonalds's across the street from it. He ran the McDonald brothers out of business.

If anyone actually knew what McDonald's has done to become the corporate giant it is now, they would spit on the food, which would probably make it cleaner.
