Get the myspacin' mug.
To hold an overall appearance on MySpace contradictory to who you really are.
Once you actually meet someone with a MySpacinality, you'll realize their completely opposite of what you expected.

This guy that goes to my school is considered the most feared gangsta on all of MySpace, but once you see his bitch ass in person you'll know he's really just a 4-foot-tall wigga with a bad MySpacinality.

Hey homie, don't start talkin' shit on MySpace when you can't back it up, lest you have a destructive MySpacinality form on you.

My friend's "about me" is so full of lies that he doesn't even know who he is anymore. The guy's, sadly, become one with his own MySpacinality.

Wanna-Be 1: Hey holmes, let's say we smoke weed and bang bitches on our MySpace so people will think we're cool little cholos. :)

Wanna-Be 2: Fo' sho' homie, let's make us some MySpacinalities!

To have a different personality over MySpace.
Sebastian is so quiet at school, but as soon as he clicks 'Log In', he's a chatterbox! He has such a MySpacinality!
