The Rocky Horror Picture Show movie warns against the excesses of mindless decadence. Frank N Furter is a sociopathic narccisist whose fragile ego leads him to commit murder and prey upon any target available sexually. He uses science to a monstrous end, creating a man with the brain of a confused child to use as a sex toy. The main characters admit to having enjoyed the party, and how great it all seemed, but towards the end they'd have to live in a state of delusion to continue living that way, that their whole being would have to be based on fleeting sensory pleasure. Frank N Furter believes this way of living can be sustained indefinitely, until it all comes crashing down, and the party ends with everybody poisoned against him.
I guess the troon pictured above missed all that and just saw 'wow there's a transvestite this was made for me'.
