It's a general assumption that any member of a horror movie forum is male, so when a female joins up it's like a woman walking into a men's shower, and will result in one of two reactions:
1. Either the male will scramble to cover himself because he's not used to being around women, or...
2. He'll prop a leg on a bench and dangle while flashing you a smile.
I think ALB's reaction was the former.
