Top Definition
A woman who changes her mind about her feelings CONSTANTLY. One second she's literally begging you to go out with her, the next minute she hates your guts for saying yes. It's worse than just PMS and lasts much longer. Being a bipolar bitch does NOT actually mean they are bipolar medically just that this is part of their personality.
My ex was a bipolar bitch. She begged for me to go out with her when I already had a girlfriend, and then when I actually dated her much later on after she started begging, she hated my guts within a week.
