Dwyle Flunking

I thought I’d heard of everything, but ‘Dwyle flunking?’
Even after an hour of web searches, all I could find out was that ‘the game requires skill, cunning, outstanding agility and a high tolerance for being slapped hard in the face with a wet beermat.’ It was to be played in Lewes, on what proved to be yet another very wet bank holiday weekend, so I could see for myself.
I’m none the wiser!
