GURL alt.:
A transvestite or drag queen who enjoys flaunting it and having a good time.
It is spelt 'gurl' rather than 'girl' because it is not a real girl, but similar enough to imitate.
Usually used in writing for context rather than spoken.
Bill and Jake were two gurls who enjoyed partying all night at the transvestite bar.
