Okay so — the specific thing where you're on an escalator and someone's standing still on the left, and you have to decide in about half a second whether you're a walker today or not, and your body actually leans forward before your brain answers. That micro-panic of posture. I was going to call it "step-lurch" but that sounds like a medical condition your uncle has. Ignore that one, I shouldn't have said it out loud before thinking it through.
