Also knowen as "the Weather Man" someone who is easily aroused in the presence of two or more guys or four second of porno. He smells like a sweaty jock strap because he doesn't know how to shower and never wears socks with running shoes. He is also knowen for breaking anything that can be broken. He is more ADD then a squirrel on red bull and loves to wallow in his own filth which is why you never ask him to clean because he will only make thing worse.
