A mythical creature, the level sixer rises above all known facebook stalkers. Pastimes include stalking people on facebook (duh) and feeding off of the souls of unsuspecting human beings.
It is alleged that a creature more terrifying than the level sixer exists in the facebook world, but nothing has been documented so far.
Guy 1: dude, she's always on facebook! that's like level 6 status right there.
Guy 2: a level sixer?! naw man that's impossible...
