The earliest reference that I could find to Postscreamelancholia in the legitimate press was in a Guardian article from last year, written by Tim Dowling (who is the Guardian correspondent who always gets the slightly offbeat stories and features).
Professor Wombliss estimates that as much as 12% of all people born between 1978 and 1982 suffer from Postscreamelancholia. "Since 1995, no music video has ever come close to the brutal shock of seeing Michael and Janet Jackson hanging around on a spaceship," he told me. "That bit with the remote control that acts like a channel changer for artwork, and the painting morphs into a sculpture? Superb."
Ian St-Yesplease is a self-confessed Postscreamelancholic. When I met him at his flat in Bumph, there was an indescribable pallor permeating his very essence.
"It's still the most expensive video ever made," he says. "Seven million dollars in 1995! That's more than ten million in today's money." He shakes his head. "Sure, other videos have made me excited, but none have matched up to Scream. Madonna's Die Another Day came close, but..." At this point, Ian trails off and stares out of the window.
I ask him what he thinks about the video for Victory, by Puff Daddy featuring The Notorious B.I.G. and Busta Rhymes. He says nothing and stares at me like I'm telling him I've just accidentally run over his dog while executing his parents for treason.
"I don't know what it is about the video," says Gordon Chippingshire, 29, of Budlam. He has been a Postscreamelancholia sufferer since 1995. "The fact that Michael and Janet play some kind of futuristic game of Pong? The gravity-defying dancing? The potent symbolism of Michael wanting to escape from planet Earth after receiving harsh treatment at the hands of the press over his paedophilia accusations in 1993?
"Or that bit when Janet's wearing a bikini and she grabs her breasts in an angry manner?"
Professor Wombliss agrees. "Yes, that bit when she grabs her breasts is awesome," he says.
