An extremely offensive term for a transsexual man or woman, or any of the transgendered community.

On the same level as "nigger", and "cunt" for most people, though, like "dyke", some of the transgendered community are trying to reclaim the word, without much success.

a man like myself who wishes to a female. Its a way of life. We dress like women, act like women, look like women and desire to be a woman.
