Trap help

So I was wondering, what's a good translation for 'otoko no musume'? I guess 'trap' would be the English equivalent but what if you're jumping in armed with the knowledge that there's a peepee under that skirt, does it still count as a trap?

I'm translating a game and it just hit me that I didn't exactly know a substitute for this word and 'girly boy' doesn't quite sit well with some of the dialogue :/

Anyone got any ideas?

For those who need a definition of the term, here is a wiki link in Japanese:
