google search anyone?? what is rip rap?
Rocks. Imagine a big pile of rocks. That's rip-rap.
riprap is little stones all broken up...
Used to stabilize beaches.
It is material put into a river channel, or along a beach to reduce erosion.
You may have seen old cars tied in the river above bridges, or in corners where the water could wash away the bank.
They have stopped using old cars, but now they use rocks that are in wire containers, to do the same thing.
I saw a rapper once who ripped his pants, could that be it?
