That is what everyone called it when I was in high school. Probably not a technical term and it is entirely possible that no one from anywhere other than nowhere Alaska has ever heard of it.
The name come from using a rosebud torch to heat up whatever part of the spring you can reach until the suspension sags to the height you want.
Cheap (especially if you sneak into the shop classroom and use the school's acetylene), easy, and fast. Ruins the ride, but "works". It was not terribly uncommon to have someone to get a spring too hot doing that and have it break and spit chunks out a week or two later.
