Learning a map without turning the evening into homework

I enjoy playing but bounce off long lineup videos. Does anyone have a low-pressure way to learn a map with friends? I would rather remember two useful things than pretend I absorbed forty.

Walk one route together and agree on names for the obvious spots. Then play a few rounds. You immediately notice which names you actually need.

We take turns explaining the route back to the group. It gets funny when someone confidently gives directions to the wrong staircase, but it sticks.

Two spots and one route is about my attention span after work. Going to try that instead of keeping a video open on the second monitor.
