The word used when confusion arises from spending an abnormal amount of time on MySpace and Facebook. It also can be used to describe what page you are on when you have two separate windows open; one containing MySpace and the other containing Facebook. "Mycebook" is commonly used by accident when the user can no longer distinguish between the two social networking sites.
Ma: What website are you on?

Paige: (Seemingly disoriented and confused) Umm... Mycebook... No, wait, I'm on both MySpace AND Facebook.

Ma: Oh... you should probably get help for that.
