Top Definition
a pile of rocks and/or debris, placed upstream in front of bridge abutments in rivers and streams, used to prevent the erosion of the bridge foundation. Also used to prevent river banks from eroding.
We need to place some riprap in front of these new bridge pilings we just poured, so they won't erode.

What completely out of touch dads say when they really mean "hip hop".
I like pretty much all music, from the Eagles all the way to Fleetwood Mac. But don't get any of that gangsta rip rap horseshit near me...

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."
