The act of dominating another person in an online game after either being tormented by them via trash talk, then slamming them in the game and shutting them up or dominating another player with no resistance. Can be used in place of the word 'jizzed' to imply the victim was forced onto oral sex with the dominator.
The origin of this word is unknown at the time. The only difference it has from the word (raged, no apostrophe) is its meaning and the apostrophe.
Lawl oh lawl I just rage'd on his ass.
I rage'd so hard.
Some_Gamer: YOU'RE FKING GHEY!
Cheater: Wow, it's just a game, stop getting so raged.
IRC_User: Dude, stop banning me, plz, kthx.
