Yep, we rodders and customizers have some of our own language.......
Tunneling, usually means you move a headlight or taillight deeper into its mount and then fill the "tunnel" with either metal or a trim ring.
Channeling is when you drop a body over the frame further than it was originally. Nowadays they call it body dropping, same thing.
Chopping, pretty obvious. Taking a section out of a roof and lowering down to a lower profile.
Sectioning, taking a metal strip from all around a body and dropping the top part down lower. Just like chopping but not on the roof, but on the body.
Frenched, is about the same as tunneling. (unless you are French, then it has a different meaning[ddev) Usually this term is used when you sink and antenna into the body, you "french" an antenna.
Suicide doors, ones that open from the front instead of like conventional cars that open from the rear. Got that name because if they open at speed.......well, you get the picture.
Peaked, refers to hoods and trunk lids normally. You weld a "peak" all the way down the hood or trunk and fair it in so it becomes a ridge down the middle.
Shaved, refers to removing chrome trim. You shave hood ornaments, trunk ornaments, door handles, chrome trim, etc.
Shoebox, usually means a 49-51 Ford, because of the square body shape, but I have seen same year Chevies called that too.
Fat fendered cars, refers to cars built from about 1935 to 1949. For example, a 48 Ford would be considered a fat fender. The years can vary, depending on the car in question.
Gow job, a very old term that referred to a hot rod that was rough around the edges. Some feel these were the early day rat rods.
Gasser, a car built to run in the gas classes at the strip. Most people envision a jacked up in front Willys, 55 Chevy, or similar car when they hear that term. The look is more popular today than ever and lots of street cars are built to simulate this look.
Deuce, is a 32 Ford.
Stovebolt, refers to Chevys from about 1950 down. They got this name because stovebolts were used to hold the early ones together.
Lakes pipes, are the chrome side pipes that run down the lower sides of customs. Lakes plugs are the same, but have a bolt on cap so they are plugged up normally and unplugged for racing.
Well, that is all I can think of for now.
