tourist
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?).
Example:
"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.
