When a guy acts like he's PMSing by being all bitchy and whiny.

When someone is acting like a complete bitch to please someone else, but while doing so, they are being a complete tool.
Robert's being a total bitchnut today. Its like shut up and stop being annoying.

Ew, did you see Karen at that party? She wanted that guy to sleep with her so bad, she was acting like a total bitchnut.
