Reverse Walting - the act of knowingly looking like or vaguely implying you were/are one of THEM by saying nothing and denying everything. e.g. Walking through the airport with a gringo moustache, sideys, dessies and a desert DPM daysack and spray tan implies you're going or returning from somewhere hot. Would that be the kitchen in Burger King?
Alternatively, reverse walting could be if you really were one of THEM, and chose to dress as a fast-food chicken-frying operative, with hushed talk in the pub about how you were first into the back of the lorry on "refrigerator-failure Tuesday", secret spices and the special techniques taught by Tibetan monks to coat a rat's hind quarters in batter to make it look like chicken.
