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".

From Old English "Twattendang", from the Viking "Twtdnglersk", meaning to hang from the rigging of a longship in an attempt to impress your shipmates.
"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."

To hold someone who is being a twat by the ankles and dangle him/her out the window or over the stairs until they promise not to be a twat any more.

We twatdangled the cleaner over the balcony until he promissed not to unplug the server to plug his vacuum cleaner in again.
