I thought I would eliminate a little confusion over some of the terms that are floating around with regard to the infamous bunnyhop.

A bunnyhop is executed by pulling your front tire up first.

A j-hop is not a new trick, it is simply what people started calling a bunnyhop when people started incorrectly calling it a bunnyhop when someone clipped into a mountain bike would lift the whole bike straight up at once.

Technically speaking, since it is not a new trick and simply a renamed existing trick, there really is no such thing as a j-hop.
