A nickname for the anus when you suddenly have to take a toxic violent shit with powerful force and high velocity. Usually these shits splatter everywhere leaving a large mess. The immense pleasure of such a brutal shit leaves you feeling very proud and confident.

Refers to someone or something that deals high amounts of damage but had a very weak defense or health. Often a term for games.

The best way to fully embrace being a glass cannon is to be very careful when you attack. Wait for an opening in which you are guaranteed a safe or almost safe hit to be as useful as possible.
John is a glass cannon, he got into a fight and with one hit gave someone a bloody nose, but he started crying the second he was hit once.

A cannon used in the Subspace Emissary, in Super Smash Bros. Brawl. Controlled by Ganon and Bowser. This was used because they were told by Master Hand (Who was really controlled by Tabuu) to create an army of ships, and a HUGE FUCKING CANNON TO BLOW THE FUCKING SHIT OUT OF EVERYTHING. This would then turn it into Subspace, but suddenly, Kirby destroys the cannon by piercing it with the legendary Kirby Air Ride vehicle, the Dragoon. The cannon then proceeds to FUCKING EXPLODE AND COMBUST ALL OVER THE FUCKING PLACE. Ganon and Bowser then admit defeat and go back to Subspace in the portal.

A cannon Rush comes from the game Starcraft. It is when the protoss race takes a probe and "secretly" starts building cannons in the enemies base. If successful, it's deadly.
Player 1: Haha, I'm going to cannon rush because I have no skill!
Player 2: Fuck you faggot!
Player 2 has left the game.
Player 1 is victorious!

About 20 dollars of PVC and a grill ignitor put together to launch a potato at high speeds in excess of 300 feet. Sounds like a gunshot. Typicly made by bored, immature teenagers, but is incredibly fun to create/play with. If you shoot a potato it'll scare the shit out of everyone within 500 feet of you.
Last friday night some nerdy freshmen made a potato cannon and shot my front door. I then went outside and ran them over in my ford bronco.
