bitch, a colloquial phrase sometimes used for a woman who is considered bossy, manipulative, or showing anger, is used in the term "bitch fest". This is due to the belief, by some, that women are better at expressing their feelings than are men.
Men, however, have been found to be as capable of expressing dramatic complaints as are women, and the term can be applied to any gathering of people where complaints are passionately expressed, whether attendees are men or women. bitch has now also become common slang for "complaint", which can be applied equally to men or women.
"fest" is short for "festival". This describes how a meeting becomes more of a show, or performance.

Serena- Let's not turn this into a bitchfest. I wanna be able to go to the movies happy.
