Last time I checked I think Foose is on the west coast... He used that word on the west coast,, I have seen it used on the south coast,, And also on the east coast... Not sure what shop's your hanging out in... But it has been used ever since I could remember..
Taken the chrome of a car and welding the seams up was called shaving the hood,, Some even called it dechroming a car..
Section is when you take a section out the car in make it shorter..
Just like some say channeling a car body,, It's the same as a body drop,,
Pancaking is when you flatten something out...
I really don't think it's a regional thing...
It's been said on to many coast for a long time..
