look up any word, like fap:
A person (generally a girl), who your friends and family warned you about and told you she/he is/was a fucking slut, But you didn't listen cause she was such a creative liar about everything in her life.
You: You're right Jimmy Cody-Lee was such a Fuckle Slut.

Jimmy: I told you man, once a fuckle slut always a fuckle slut.

You: Some people just gotta learn about fuckle sluts the hard way.

Jimmy: Yup, just listen to your friends and family next time someone tells you the girl you are considering dating is a fucking slut.
