orgasm drunk
That moment after having an orgasm where you think you really like the person, and then you take a nap and wake up and realize you were just orgasm drunk from all the feel good body chemicals that having an orgasm produces and that you really don't like the other person at all, and you should never, ever make promises while orgasm drunk.
I thought I wanted to go on a date with this guy, but then I realized I was just orgasm drunk.
