Slut

Also known as slattern

Slut (archaic: slattern) is an English-language term for a person, usually a woman, who is sexually promiscuous or considered to have loose sexual morals. Predominately used as an insult, sexual slur, or offensive term of disparagement, it originally meant "a dirty, slovenly woman". Rarely used in reference to men, clarification such as male slut or man whore may be warranted.
