Last October, Metro kicked off a quirky campaign to encourage commuters to travel more safely; basically, they coined new words to describe safety-enhancing practices and shine some light on those whose actions made riding the rails that much more painful a process. They started small, with four words — PlanBdextrous, referring to the ability to map out an alternate route home; Sumpnspicious, those suspicious actions and occurrences that should be reported to Metro officials; Conseaterate, the act of giving one’s seat to someone in need of a seat; and Doorker, the person who blocks the train or bus doors.

The ad campaign never much took off, with signs bearing the words and their definition appearing only sporadically on the system’s many trains. But yesterday we noticed that they had added a new word to the list, this one appearing on an Orange Line train:

Escalump — Person who becomes a human speed bump by suddenly stopping at the top or bottom of Metro escalators.

If we had to hazard a guess, we’d say that this one was pulled out just in time for what is sure to be a summer packed with tourists unaware of Metro’s unwritten yet strict codes of conduct. We’d still like to see Metro take on some of the words we made up, including the following favorites:

Sophmapic — A term generally describing the consistent need of inexperienced Metrorail riders to check the system map and constantly ask, “Is this our station?”

Constairpation — The human traffic jam created by that one Metrorail user that by inexperience or obliviousness to Metro etiquette stands on the left side of a given escalator. See also “Tourist.”

Premature Boardgasm — When a train stops short at a station, only to move forward as users frantically run to catch up with the train’s lead car.

These would look awesome in print.
