this retarded wooden piece of crap catapult built by schillywilly. youre supposed to be able to launch things with it, but when you try to shoot a brick it just comes crashing back down , causing the trebuchet to break into a million schmelly pieces. so then you need to burn it because its worthless.

When you put your dick between your legs and a girl starts to give you head from behind. She has her nose in your asshole and throws up all over your dick after you fart on her. Then you turn around and open your legs and your dick slings forward like an eskimo's trebuchet and puke splatters all over her face. Boom.
- Hey Billy, why does that girl have puke all over her face?

- Aw shit son, I just gave her an eskimo trebuchet.
