Cork is a backwards spin in which you are off axis. Bio is a forward spin where you are off axis. Misty is a front flip of sorts with spinning. Rodeo is a backflip of sorts with spinning. These are not exactly the perfect definitions, but they are the basics principles.
Corks are for wine bottles, Bio is a shorthand term for the study of life, Misty is the ginger girl from pokemon and rodeos are for hicks and their chicks!
