Pick-up line used by a chubby chaser. When phrased as a question, it loosely translates into "I want to sex you, you big fat fatty, and nothing more. Are you interested?" Is particularily effective after excessive drinking, but is equally likely to end with a drink being tossed in the face followed by a slap. Also popular among frat boys, with the latter outcome most likely to occur.
Hollywood: "Moo?"
Fatty: "The fuck did you say, asshole?"
Hollywood, laughing: "Moo?"
Fatty: "Alright daddy, but keep it on the brown low."

A female breeder. Short for Moomy, like "Mom" is short for "Mommy." So-called because such women drop offspring like cows do, seeming to have little other purpose in life, and sometimes conspicuously breastfeed them in public. They often also bovinely ignore them...unless you attempt to discourage their crotchfruit from screaming or otherwise misbehaving in public, in which case they will begin lowing like an angry cow whose calf has been threatened.
That stupid Moo was letting her little bastard tear up the entire supermarket while she stood obliviously in the frozen foods aisle.
