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.
A door wall is a sliding-glass door or patio door. The term is yet another example of banal Michigan vernacular, where in the residents latch on to company names, trademark names, marketing terms and product names from local companies. The terms become embedded in the local vocabulary and eventually become accepted as actual valid words and phrases. In this case the term comes from Wallside Windows in Taylor, MI (a large window manufacturer), where 'door wall' is their created word for sliding-glass door.
