Sock heads are fans of the short-lived MTV
show, Sifl and Olly
Sock heads refer to anything good as "cres" or "crescent fresh". They refer to the bad as "Boshwag" If something makes them the slightest bit happy, they yelp out a staccato "ROCK!" They are also prone to chasing soap bubbles.
Fake blood rocks them like the real thing.
It takes a special kind of stupid to be a Sock Head: a stupid that one can be proud of.
