But if you happen to be a woman, claiming to be a lesbian (most especially, a man-hating lesbian with a big threatening collection of battery operated implements that no human man could ever hope to compete with...) can sometimes help get rid of the particularly persistent "Hey baby you must have a mirror in your jeans because I can see myself in your pants" assholes at bars. Or laundromats, or whatever. ("Hey baby, did you make that shirt? No? Well, you did when you put it on!")
