What's on your mug?

Online gaming shorthand for "are you mad?" Used as a taunt after pwning an enemy or messing with someone.

Red player: "I can't believe you just killed me with one hit! Are you cheating?" Blue player: "umad?"

Used in Online Gaming especially any kind of FPS. Specifically, a taunt, designed to incite rage. Mostly for lulz. A form of gaming trolling with the intent to anger another player into behaving childishly. Esp. with the intent to get them to Ragequit.
