Meaning fucking cunt slut whore. Can be used for all genders.

A person so immoral they do not care about anything or anyone. Wouldn't care if they fucked six persons in one evening without protection and without telling the others they suffered from HIV/AIDS.

A person that only cares for themselves, lies towards all others, and is generally really fake.
Guy 1: "Dude, don't you know that girl is a fcsw?"
Guy 2: "Urgh, I do have some standards. Let's find a crack whore instead"

Woman 1: "Hhe's a true fcsw"
Woman 2: "Yeah, totally fake and dishonest. Used me for over a year, and didn't care a thing about me"
