An individual who is not only an imbecilic they wield their idiocy as a weapon and often fall into positions of power in which they can corrupt and decay the previously working systems.

Absurd stunt involving David Blaine hanging upside-down above a NYC ice-rink for a couple of minutes, duly extended to mean any publicity-grabbing gig exposing the protagonist as a complete "twatdangle".

"Hey, did you see the upside-down David Blain thing? That was like so cool."
"Nah, the guy came down after two minutes for a piss. It was a total twatdangle."
