A term used when someone is acting like a bitch, therefore exuding nasty or unwanted energy. Or opposingly, when someone is acting positively like a bitch, exerting confidence and dominance.
The scenario should reflect the type of bitch behavior one is giving. Here are two examples:
"Alex is spreading nasty rumors about Lexi, that's such bitch behavior"
"Andrea gave bitch behavior when telling off James for what he did, love her for that"
