A noun used to describe a situation in which a girl gives a guy false impressions of attraction. So the guy proceeds to try and start a relationship while the girl suddenly changes her mind and fucks him over, leaving him to try and figure out what the hell happened.
A girl tells me she is interested. I try and start a relationship because she says that is what she wants. She then changes her mind one fucking week later and wants to be just friends again. That is a bitchtacular at it's finest. Thanks alot kaitlyn, you've inspired me to invent a new word.
