Show off naked at the beach

How is it 'showing off' when there are no people around?
There are people around. However, I am not taking photos of others without permission... and I'm not about to ask at a nude beach.

But sometimes folks show other people off in the distance, for instance, so we know they're out there naked (maybe hard?) and others can see them
