common term for a person who shows lots of anger/grumpiness. When you perceive an angry person complaining or ranting, usually "Grumpy Cannon" is said to annoy/aggrivate them.
The term comes from a Megaman type game, as the thought is that if you beat the commonly angry person, you will inherit their grumpy cannon.
