​Playing 'possum simply means playing dead. It refers to the most popular and effective defense mechanism of the marsupial when faced by a formidable predator.

This simply means that such an event is an opossum literally fainting out of sheer fright. In this reaction, the creature mimics an actual death by falling dead flat to the side, baring teeth matched with foam at the mouth, and a nasty stench of death from a fluid excreted by  the opossum's anal glands. The creature remains in this seemingly lifeless state from several minutes to as long as four hours.
