Yamaha

The roller coaster enthusiast's roller coaster rating scale, derived from the expression "Yaaa! My hat!" refering to the lost of a hat while riding. The number of Yamahas indicates the speed and quality of a ride, the greater the number, the better the ride. The antonym is Nomaha.

That child's roller coaster wasn't even worth one yamaha.
