Any individual who displays no regard or knowledge for the unwritten rules of a location or city. Tourists in London, for example, frequently stand on the left hand side of escalators on the tube (a serious no-no), stand directly in front of the train doors with large rucksacks (again, you just don't do this) and take photographs of them halfway out of a telephone box as though they were appearing in a Broadway musical (does anyone do this anywhere at all?).
"What's that? Stand on the right? No, I think I like the left hand side better. Who cares about those other jerks wanting to get by? I'm a tourist, they should wait." - the primary cause of rioting on the London Underground.
The world's first, greatest and only 24-hour-a-day rolling news channel. Only it has commercials. And shit journalists with corporate agendas. Basically, the Western World's equivilent to Communist Chinese TV.
"And now on Sky News, there's trouble at our rival station BBC News 24. Hahaha! Serves them right. Ahem! Where was I?"
