A chick who is on the rag or is just a bitch. One who came out of the womb angry at life. Chicks can be inherantly born a koozebag or become a koozebag temporarily for many reasons such as an upcoming wedding or the fact that they are on or soon will be on their period.
Guy #1: I politely asked Jen a question about sending me a vendor's contact information and she copped a major tude with me!
