1. In generic usage, the female counterpart of a bro
. Where a bro is overly male, overly stupid, and often intoxicated, the biddie is overly female, overly stupid, and often intoxicated. May connote a distorted fashion sense, sense of direction, and/or sense of time. Pejorative (what a biddy!) but can also be used in a friendly context.
2. A potential for sex. This usage emphasizes the positive aspects of femininity (being hot, being available) and does not always (but can) encompass the more pejorative connotations of the word.
3. A total mess. This usage emphasizes the pejorative aspects (falling over, poorly/sluttily dressed, drunk) and does not always (but can) encompass the more complimentary connotations of the word.
4. Also, anyone who goes to American University in DC.
1. Look at those biddies with their little black dresses. They're a hot mess.
2. Yeah, I wanna take *that* biddy home tonight.
3. Hahaha, those biddies are trying to swipe into the dorm with their credit cards.
