Gender Queer?

After a quarter of a million hits here (thanks to all!), it may be time to take a look at another term which I have seen a lot of but never really looked into it's real meaning.
The term is "gender queer" and here is one definition from the Urban Dictionary:

"Genderqueer is most commonly used to describe a person who feels that his/her gender identity does not fit into the socially constructed "norms" associated with his/her biological sex.
Genderqueer is an identity that falls anywhere between man/boy/male and woman/girl/female on the spectrum of gender identities."
Example: "Mary doesn't feel that s/he fits the mold of any one particular gender; therefore, Mary identifies as genderqueer".

And another:
"Any position in a wide variety of gender identities, spanning the spectrum between male and female. A person who is Genderqueer is not transgendered, though the option is open to transition. Being genderqueer has no bearing on sexual identity or orientation."
Example: "Eli might have a woman's body, but ze doesn't feel like a woman or a man. Eli is genderqueer."

At the risk of starting another worthless war on words here and launching yet another term (which is new to me at least)-I definitely will revisit the term in the future!
