Twant 

Part twat and part cunt - a twant is someone behaving in a manner that is both stupid AND bitchy.

Twant - someone so full of themselves that they aren't aware they are actually stupid. But they are aware they are bitchy and enjoying being that way for no reason. While it may more frequently apply to women, men can also behave as twants.

Twastard

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!

Invented by Eve and Dunnie (well more eve!)

"OMG You are such a TWASTARD!"
