A con I was at had a "captain jack flirtation bingo." You were supposed to flirt with someone, and then get them to sign your bingo card.

Two very young women came up to me (I was corsetted) and started touching me without permission, though not my breasts. I wasn't afraid, but I was creeped out and pissed off, and I told them that they were behaving badly. I was probably to surprised and creeped to say why, but yeah.

It's not ok when strange chicks do it either.
