Acronym, meaning Bitch, Piss, and Moan. Used to indicate excessive complaining.
Guy #1: Why are you back so early? I thought you had a date or something...

Guy #2: Yeah, well I dropped her off on the side of the road before we got to the restaurant. She decided to BPM the whole way, and I had enough.

Guy #1: I don't blame you. She sounds like a bitch.
