A play on the word bizerk; combined with the Son of Sam, David Berkowitz to describe a state of insanity. Most effectively used as a verb, but may also be used as a noun.
Ex: Hey, did you see Jimmy go bizerkowitz yesterday after that dude cut him off??
or
Hey, check out Bizerkowitz over there freakin out on the cashier.
