To have had sex with someone. There are two connotations associated with this term; the first implies that the person with whom you had sex was cheap and/or easy, the second that the relationship was totally casual with no strings attached. In both cases it is understood that there was little or no emotional attachment or respect involved, and that the sex was hard and intense.
