Psycho Skinny
Psycho Skinny: the drunken (sometimes high) alter ego of an extremely emaciated 6'4" young man that manifests itself instantaneously without warning or any perceptible trigger.
Daryl was acting normal when, all of a sudden, he told everyone in the bar "fuck you" then bolted out the door...the bartender responded well i guess Psycho Skinny has left the building!
