Sketch-Nasty 

A trick in any board sport (Snowboarding, Wakeboarding) that is executed but doesnt look very good.

The opposite of steez

Arms will probably flail about
not very high air and also bad and sloppy landing

Snowboarder 1: Did you just see that Back 7

Snowboarder 2: I did but with those arms flailing and the sloppy landing it was Sketch-Nasty
