clip - a whole part of another car. you hear of a lot of guys buying TT front clips for their swap. a lot of times with a very damaged car they will weld in a large portion of another salvage car. This will make a complete car, but you will usually be able to see weld lines on the underside of the vehicle.
clipped - minor accident with no major structural damage. This is not an official definition, this is just what I have always heard all the body guys saying.
