Girl coming from a broken family (usually related to fatherly neglect) that dresses/acts innapropriately to gain attention from others because she had never gotten the attention from her family
A girl who likes to have sex, and loves dicks. But a lot of them also like cunts. A slut basically just likes to orgasm. However she reaches that orgasm. She's not bothered, which is why they're often thought to be disgusting.
An very promiscuous individual. Has slept, and continues to sleep, with an insane number of people in a short amount of time. Can present themselves as either hot or gross/trashy.
Usually this semi-derogatory term is directed towards females but is often used to refer to men as well (many players fit in this category). I personally don't gender discriminate when using this term.
I think of male and female sluts to be no different from each other except for gender.
A couple descriptions of "slut":
Roxy's probably slept with about a hundred people in the past year. She's really racking 'em up!
That player's probably slept with about a hundred people in the past year. He's just a hot piece of ass in my book.
A women who is most satisfied when she has at least one ball in or around her mouth/vagina/anus, but she usually isn't satisfied because she's an ugly bitch and no one wants to fuck her because she's so goddamn ugly and slutty.
"Look at that slut."
"Goddamn she's ugly. I bet you a dollar she'll let me cum in her hair."
