A couple of decades ago, LA Times columnist Jack Smith covered this topic for a few weeks, and a lot of readers sent in suggestions. My favorite was by a JPL engineer, who submitted a NASA style acronym, SPLAF. It stood for “simutaneous pedestrian lateral avoidance failure”.
I suppose most of what’s said in the column goes for indoors too. I haven’t been in the windy city in ages, but here on the east coast the dance doesn’t happen on the sidewalk very much. If you’re indecisive, the other guy will be decisive anyhow and mow you down.
Since moving back to the US from a country where people drive on the left, I’ve noticed this hallway jigjag is more of a problem. It was a problem when I first moved to the English Caribbean, too. I think people instinctively walk on the same side they drive.
I know it’s not the perfect fit as in definition, but what about the already-in-existence word “sidle” ? It makes no mention of a dance, but is essentially an accurate description of what’s going on.
