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.
Mary doesn't feel that s/he fits the mold of any one particular gender; therefore, Mary identifies as genderqueer.
Keezer is a remarkable kid with an extremely sarcastic/hilarious/hearty laughter and is believed to make a great Santa Claus. He is immensly tall, and when you tickle him he will kick you in the head. He has a huge leather jacket, and if you put it on, it will look like you're swimming in it. He personally enjoys my marketing idea about cellphones and internet hook ups.
Keezer: Cows can't use phones or type.
Marisa: I'm a cow with marketing skills.
