Rainbow Serpent 

It's an aggressively homosexual aboriginal that attacks you (in the binung) while you are unconscious. The nightmares that follow is what they call the Dreamtime. You may encounter it during a coroboree.

Person 1 : are you OK?
Person 2 : I feel fucked after last night's party.
Person 1 : probably that Rainbow Serpent mate, now you understand the dreamtime.
