A myspace whore is one who spends most of their waking hours on myspace.com.
They have thousands of friends, only because they 'whore' themselves in bulletins in a pathetic attempt to gain more friends and look cool on the internet. Upon gaining more friends, the myspace whore convinces these new myspace friends to whore them like there's no tomorrow.
Myspace whore can also be defined as one with very little exposure to the real world.
Myspace whore: "WHORE FOR WHORE! I HAVE 5K FRIENDS! ADD ME!"
Other friend: "OH wow, I should whore her. I hope she whores me, she has 5k friends! Maybe all 5k of her friends will add me! Then I will be amazingly cool! I'll be an e-superstar!"
