First, you have to see it to believe it. Watch any episode of Ross Kemp on Gangs or Extreme World. He doesn’t walk; he swaggers with a side order of "I’ve just sat on a cactus." There’s a distinct side-to-side roll. His head stays suspiciously still, like a robot trying to look casual.
It’s a power walk. But the power seems to be coming from a dodgy hip. You look at him and think, "Mate, did you forget to take the hanger out of your trousers?" It’s iconic, really. Unintentionally hilarious, but definitely iconic.
