A promiscuous female, notably plastic, stuck-up, and/or drama-causing.
Usually suburban and college girls fit into this category, as well as groupies.
Also is not the type to wife up; more like a quick fuck at a party to be followed by days of drama.

(Believed to originate from the idea of "causing ripples" (or 'making waves'); also rhymes with "riff-raff.")
"I told him not to fuck her. Now that little rip-rap is going to cock block him at every party."

"Who was that girl you were talking to?"
"Just this lil rip-rap I'm gonna get with."
