When the nutburgers start shedding clothes in a violent situation, it's much like them holding up a giant flashing neon sign that says "somebody is going to die today". At this point they are completely out of their minds and beyond all reason.
Maybe cocaine intoxication: we saw this in Miamia lot. They “burn up”, and think removing their clothes is the answer. One ran into Palm Beach surf and drowned.
