I'm female and I'm going as Pinhead, is that also slutty? Good grief it's a costume..and what do you presume as slutty (I hate that and the c word). Just because you said this..I'd dress (or undress) in the sluttyest outfit possible. So if your boyfriend dresses in a like costume what do you suggest the ladies do? I bet your answer would be "consider yourself lucky to be with such a guy" or "hot guys rule the world" or even better "you can look but don't touch..okay you can touch". Pfft, male chauvinist..get a grip.
