Noun:
Pronounced with a short a, rather than a short o (I have no idea where American directors get their pronunciation from), 'twat' is a rather vulgar word of British origin that refers to a woman's sexual organs.

A person can be a 'twat', the same way they can be a penis (see dick) or something used for cleaning said twat (see douche). It is usually used to mean someone is stupid or mean.
Me: I am a nice, well-behaved girl. I refuse to use such offensive words merely for the purpose of giving Urban Dictionary an example of how to use it.
Person reading this: *cough* Twat. *cough*
