"Wunch"

While listening to Simon Mayo the other day, there was a nice moment when he became a bit concerned that the person who had called in was going to be rude about the bankers. The person on the phone says, "No, I'll just call them a 'wunch'." Mayo did not know what he meant and cautiously asked him to repeat it. "Wunch," the caller replied. "A wunch of bankers". A google search confirms that the word has been around for a while, and even finds its way into the Urban Dictionary.
