Bitch duck is a cartoon character Peter Griffin from the television program Family Guy created for his show "Handiquacks". She likes to have no fun, and ruins others fun.
The ultimate insult. A person labeled as a "Bitchmilk" is one who is whiny, snobbish, complaining, pessimistic, cowardly, bitchy, really bitchy, and cunt-ish.
In most basic terms, the opposite of a badass. It describes one who, while drinking with friends, does not have the testicular fortitude to finish one's drink.
Short-hand for the word floccinaucinihilipilification, meaning the estimation of something as valueless (encountered mainly as an example of one of the longest words in the English language).
