An awkward interaction when two people encounter each other in public. Each person attempts to move out of the other's way but move in the same direction, failing to judge the other's direction of movement. The situation can often result in deadlock whereby the only way to extricate oneself is to vocalise an apology and agree on each person's continued route.
Even though the pavement was empty, I still managed to quelch with an old man.

That was an intense quelch. We eventually had to agree that I would go this way, and she would go that way.
