A cunning mixture between Bastard and Twat, used when someone is bad enough to be both at the same time. Also as it is not technically a swear word, no one should have any objections with you shouting at them!
The name (not so affectionately given) for the members of the realm Quel'Thelas on World of Warcraft.
This is a Latin American realm and most of the members don't seem to speak english at all and/or are horrible at understanding the mechanics of the game; often leading to an extremely frustrating time for the english-speaking majority of the population.
Person1: I'll be ready for an invite in a second, our tank in this random is another Quel'thatard so hopefully we can win this...
Person2: Some of the UD editors are Quel'thatards too! They may reject this definitioneven though it clearly fits every guideline!
