A superior piece of medieval siege weaponry which is capable of hurling ninety kilogram projectiles over a distance of three hundred metres using a one-tonne counterweight. Capable of smashing castle walls with ease, unlike those inferior catapults.
Plebeian: The catapult is the best piece of siege weaponry in history.
Dominus: Can it hurl 90kg projectiles over 300m using a counterweight?
Plebeian: No...
Dominus: Then the trebuchet is vastly superior.
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 splattersall over her face. Boom.
Verb~ The act of masturbating until the point of climax with the penis between your legs and pointed backwards. Upon climax, one releases said penis, causing a "trebuchet" like motion and fires the ejaculate onto ones own face.
A category of hurling device (catapult), consisting of a large beam, a sling, a counterwieght, and a frame. The beem is mounted to the frame by an axle about 1/3rd to 1/5th from one end. A sling is attached to the long end of this beam and a counterweight to the shorter end. The machine is then cocked by pulling the longer end of the beam or throwing arm downward and locking it with some sort of trigger system. Upon release, the counterweight pulls on the short end of the beam causing the long end to swing upward and forward, followed by the sling. The sling then releases the projectile and hurls it toward the unfortunate target, whatever it may be.
The act of removing a mans underwear whilst he has an erection. As the waistband slides down the erect penis, the penis will abruptly fly up, smacking the man in the stomach like a medieval catapult or "trebuchet."
Another of the thousands of euphemisms that describe male masterbation. The term comes from the act of loading a catapult like medieval weapon called a trebuchet which used counterweights, and mechanical advantage to hurl things long distances.
