Most of our younger techs may not remember the western series
Bonanza (originally broadcast Sunday nights on NBC from 1959-73), but in the opening credits, a picture of a map is shown with a fire burning through it. This fire burns from the middle out to the edges resembling what we might see when we put a highly saturated gel in front of say, a 360Q 6x9 @ FL. Any time you see a fixture melt through a gel starting with a small hole and getting larger, you can describe this as the gel "going Bonanza".
