A cross between a stumble and a hurry-up. The effort made by people when trying to give the impression of hurrying up while walking without actually speeding up. It typically involves exaggerated leg movement, perhaps an attempted skip or two and an apologetic half grin while maintaining the same forward speed. Used a lot by people crossing the road in traffic.
Oh for goodness sake, get a move on, don't spend all day sturrying across the road!
