I'm reacting against the word "intuition" here. Nobody said it isn't a wave. But it's not like a wave as our intuition says.

(Though it does not _always_ look like a wave - check out the timelapse video from Kuji harbor: https://www.youtube.com/watch?v=M1B1J6sgFxk - that's why you'll sometimes see people talking about it looking like a (very) high tide. As an example of the nightmare "wave" which doesn't stop, and is thus un-intuitive.. https://www.youtube.com/watch?v=3618dZoiaPE which is incidentally also from Kuji, but from 2011)

I know what you’re talking about. But intuitively it’s still a wave.
