Get the cyber mug.
Internet role-playing, also known as "cyber sex"

Usually curious tweens/teens, people can't get a girlfriend/boyfriend in real life, or 50+ pedophile/child molesters engage in this activity.

You can find people who want to "cyber" in chat rooms, and sometimes through IM or other social networking site.
(You can get banned for initiating this behavior in some sites.)

It's basically self-masturbation while sitting at your computer.

Cyber + Chatrooms = No Life
lonelygurl: hey, wanna cyber?
lonelyboi: sure!

lonelyboi: *enters you*
lonelygurl: *moans*

Later that day...
Lonelygurl: I lost my virginity virtually last night!
