I dunno. Lots of places, even, are named really dumb shit in their native language, or in old english. Places that are just named like, Johnstown, or some shit. Johannesburg. Hillsborough. Portland, land of the ports. These are really dumb names, they're kind of akin to the modern convention of naming the streets of suburbs after the trees that we cut down for the land, like Pine street, Fir street, Douglas avenue, and don't get me started on Main street, or streets that are just numbered in order.

Basically, I guess my point is just that everything has a stupid name, I think it just sounds cooler when it's nonsense (perceived, or otherwise) because it becomes associated with the work on it's own, rather than being associated with external stuff which may or may not be descriptive of the work.

That's the beauty of it, I didn't know that jujutsu kaisen meant such a stupid name, nearing the irrelevancy of tile as God of Highschool. If it sounds whatever but you don't know its stupid, it isn't.
