A guy who hangs around your girlfriend as a "friend" who is really just waiting for the day when you and your significant other are on the rocks. That is when he swoops in to make a move, as the comforter, supporter, and basher of her current bf. Women are oblivious to them entirely.
Oh you need to talk to Matt? Jeeze that guy is such a lurker!

Someone who is constantly on myspace looking at the same people that they don't know over and over again to see if they have new pictures, who their friends are etc. etc.

Lurkers often lurk in packs, to show their fellow lurkers their lurkees, and to show off their taste in lurkees.
Koala is such a lurker, every night she sits in front of her laptop on myspace, lurking people she suspects may be cooler or prettier than she is.

A Lurker is like a creep he is the kid that sits in the back of your anatomy class. He has large but sunken in eyes,greasy hair, a pasty complexion, and a crooked smile. When he laughs he sounds like he's hissing. He also offers you rides home to and from school even though he lives 15 miles out of the way. But thats ok because he never sleeps. His biggest fantasy is to be your number 1 stalker.
"Look at that goddamn Lurker, get out of my Art Room Lurker."
"I'm not turning my back to you for one second Lurker."
