A term coined to describe "Sunday Londoners" - the non-commuting public who who travel into London on a weekend, particularly on Sunday for tourist-y reasons. Identified by their failure to understand the etiquette of public transport journeys and are most likely to be wearing an I Heart London sweatshirt. "Sundoners" cannot read signs while walking and tend to congest at every orientation point of the journey.
The Sundoners stood side by side, holding hands on the Escalator ignoring the Stand on the Right signs and clogged it up for everybody else.
