A form of quitting from a person's workplace of employment after being treated like a douche by management and bosses. The employee becomes so enraged by management and retarded customers that they take the persona of a dragon or similar mythical creature and resign from their job. Objects tend to be broken during a rage quit.
Petunia was so pissed off by the mentally insane chat users and betrayal by the Moderation Manager that she rage quit yesterday. She broke shit and everything, it was wicked.
