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!
Player 2: Fuck you faggot!
