Fiasco: Touring Rock Band.
Rodney Rok and Alex Pluto are a heavy metal act who only play well when they're baked. They're also lovers, but they keep their sexual relationship in the closet for fear of alienating their fanbase. The name of the band: Cocked & Loaded.
After scoring a bag of PCP-dipped weed from some local teenagers who assure them it's "a gift from God", both of them begin tripping balls, and it's not fun. Rodney hears the universe ringing in his ears and stumbles into a ditch beside the road, calling out "Alex - where are you?"
Alex responds "God is trying to kill me!" ...and then a second later, "SATAN - YOU WERE RIGHT!"
