When a member of the general public appears on the big screen during a tennis match at Wimbledon and acts like a total dong! An example of this would be flailing their arms about like a moron and mouthing "mum i'm on the telly!"
Dan: Oh what a spiffing...MUM, I'M ON THE TELLY!!!

Stacey: Oh Daniel...please compose youreself, you are acting like a total Wimbledong!
