When a person, usually male, on the internet changes their listed gender to the opposite one on some website. Some people only do this for attention, but there are others who feel seriously about it and want to begin living on the internet as the opposite sex since they can't do it in real life.
Did you hear about John's internet sex change? He changed his gender on Last FM to 'female' and has been acting like he has always been a woman. Maybe he has been, it's the internet so you can never be completely sure.

The feminine equivalent of the internet tough guy. The internet sex kitten is a female message board poster who plays up her sexuality in an attempt in an effort to become popular with the male posters on the forum, and because internet message boards are often populated with lonely nerds, it's usually not long before she has her own following of drooling fanboys. Internet sex kittens will often exhibit any combination of the following behaviors:

- She'll claim to be bisexual and willing to participate in threesomes.
- She'll flirt shamelessly with male posters.
- If she's already in a relationship, she'll claim that her man is completely satisfied with her and that she gives him hot, wild sex all the time.
- Speaks candidly about her blowjob skills, or other sexual techniques.
- Admits that she loves watching porn.
- Posts pictures of herself looking into the camera with a sultry gaze (if the picture is from the neck up, you can bet that she's fat).

Ultimately, the Internet Sex Kitten is a combination of an attention whore and a cock tease. Lonely male forum posters will jump through hoops to win her approval, but it's rare that they'll ever interact with her outside of a message board or chat room.
"HottieGirl69 just started a 'favorite sexual fantasy' thread and already her fan club has turned it into a online flirt session. I'm getting sick of HottieGirl69 and all of her Internet Sex Kitten behavior."

WOW. You are more bored than anyone in this universe is. You've just written all UD categories in the search bar. That's amazing, now go making your maths homework for the next day.
When I was bored to death, I looked in Urban Dictionary and saw that "Categories" option. I pointed at it and saw College Name Drugs Religion Food Sex Internet Sports Music Work, and it was really funny, so I wrote it in the search bar and pressed that + button.
