gymnot
Somebody who thinks they are amazing at gymnastics, when in reality they have never taken a single gymnastics training session or have only been to one, they have a tendency to say they are able to do what a gymnast can do, ie. Splits, or they think they can do something perfect when they can't
Gymnot: Look! I can do the splits!:D
Gymnast: You're at least 10 inches off the floor:/
