The term car fax for the information about a car that has been used! Ask a girl if she has any sex fax, meaning who has she slept with! I would ask this question before each act of intercorse with a new girl!
Boy: Girl you got an sex fax!

Girl: Yeah I have slept with two other guys no diseases!

Boy: Alright let's do this!
