Yesterday I was talking to my boyfriend and I mentioned that I had seen a girl with slutty pants. I was shocked to discover that he didn't know what this term referred to. So, knowing it would take me a while to come up with an efficient explanation I looked an E2. Much to my disappointment, I soon learned that there was no node on this topic! The only one that comes close is bitch pants, and even that is not quite the same as slut pants.
Slut pants are pants (or shorts) that can either a) be visibly taken off quickly or b) show off every curve of your womanliness. (referred to as camel toe.)
An example of pants from category a would be pants with a zippered crotch (shown in the movie Coyote Ugly) or pants without a snap or button on the top (eg. a tie up fly).
An example of pants from category b would be pants made with stretchy material (eg. spandex).
A woman could be seen anywhere wearing these, but most likely at a social event with an even gender mix.
