french
 v.— «Add this to the list of terms that no one seems to know the origin of. Frenching is simply smoothing a body element into the body so it’s faired in—most often the headlights and tail-lights of a vehicle. To french headlights, the headlight ring or bezel is welded solid to the body and the seam filled, and the headlight buckets are modified so the headlight can be removed and adjusted from the rear.» —by Gerry Burger, Steve Hendrickson Hot Rodder’s Bible , 2001.
