ladybrain

responsible for any and all borderline crazy, insane, and potentially embarrassing activity that a woman engages in usually during of after some type of "dating" encounter with a man; caused primarily by interactions with men who are emotional trainwrecks or emotional vampires or after a gaslighting incident

Ladybrain took over and I cyber-stalked the random girl who smiled at my boyfriend and even though I didn't know her name I found out who she was, what she ate for dinner every night last week, and that one time she "liked" my boyfriend's facebook status. Maybe he is cheating on me with her. The internet is amazing!
