I'd call it the Tamister. xD
First, it'd be a calm, smooth, slow ride up a 30-metre-high hill, but when you reach the top, it stops moving.
THEN IT ROCKETS DOWN THE SLOPE UNTIL EVERYONE GETS A CONCUSSION! Muahahahahaha!
Then a huge zig-zag pattern, then 10 small loops, then finally it ends with...
ANOTHER HILL! WHOO HOO!
