An eye-opening crappy experience that cures a person's crush. Usually happens on what the first person thought would be a date but turned out otherwise.
Guy A: "Dude, how was your date with Brandy?"
Guy B: "Awful! I spent the whole time painting her apartment while she talked on the phone with some other guy. I'm totally done with her."
Guy A: "Wow, sounds like quite an antidate."
