Cockney rhyming slang for "to go wrong". Really? I can't find any quotes anywhere. But then, perhaps I'm not looking in the right places. -- ALGRIFtalk 11:01, 24 August 2011 (UTC)
From Google Books:
"after half an hour he was experienced enough to know it had all gone Pete Tong and simply stopped using his phones", Starfishing By Nicola Monaghan, p181
"it didn't take a brain surgeon to realize that things were obviously in danger of going Pete Tong", Sniper One: The Blistering True Story of a British Battle Group Under Siege By Dan Mills
"Things started going Pete Tong as the superficially attractive two- or three-year fixed mortgage deals ran out, interest rates went up and the housing bubble inevitably burst" Cityboy Beer and Loathing in the Square Mile By Geraint Anderson
I've certainly heard of it. And I'm a northerner, not a southerner. --Mglovesfun (talk) 16:03, 24 August 2011 (UTC)
