fiddy

A small kids motorcycle (usually a honda crf50), that has been transformed into a 65+mph mini-moto that sits a few inch's off the ground and can be jumped or raced by adults way to big for it.

Motocross rider 1: Hey did you see that little fiddy flip across that double?

Motocross rider 2: Yea, that was insane.
