Top Definition
An annoying female who gives the impression that she is always on her period. They stomp around tutting all day, have mood swings constantly and will snap and cry at the slightest provocation. If you think you are currently seeing one of these ladies, get rid!
Neil: I can't take it anymore, she's doing my head in all the time, everyday.
Nigel: I warned you there'd be trouble with her, she's one of the biggest rag monsters I've had the misfortune of ever meeting!
