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.
