An chronic disorder, usually the result of having a vagina. Symptoms include a heightened sense of drama- especially when none exists, bitchiness, poor sense of direction, failure to understand simple instructions like "make me a sandwich, now!", and neediness. People with the disorder tend to cry, and make stories up.
Deep penetration can sometimes alleviate the symptoms for a while, but tend to result in addiction, and "emotional dependance".
Can happen to especially whiney guys.

Guy- I do respect you, but you have twat syndrome and can't tell. Haven't we talked about this before?
