1. Dressed up as pregnant, drinking & smoking at the bar; made a lady beg me to stop
    She didn't get the whole Fake Pregnancy thing; my BF and I took it all the way "I'm European, your American rules are so strict" (I am not and do not agree).
  2. When boys asked what a succubus was last year, I'd say "semen demon" and ask them if they wanted their soul sucked out.
    I think the fact that I was so forward scared them more than my costume.
