Someone is trying to show off martial arts, but they just look goofy. They flail around, fall over, smack into stuff, and a whole bunch of other things.
Contrast Martial Arts Do Not Work That Way
- Who Is Harry Crumb had the titular Harry trying to show off akdo, and instead knocked something down (can't remember the scene too well).
- Sokka of Avatar: The Last Airbender, when he was trying to find a good weapon. He kept falling over or smacking himself until he found a sword.
