escalator overachiever 

Someone who feels they must treat an escalator as a staircase, bringing guilt to the rest of the parties on the escalator, unless they also do so.

Jane: "Why is that girl bounding up the escalator like it's a flight of stairs? She's making the rest of us look lazy for just standing here riding it!"
Jill: "She's a total escalator overachiever."

Jim: Oh you didn't know? Turns out she is a closet overachiever.
