I dunno, I think they’re kinda … neat, I guess? Like, yeah, they’re technically pretty ugly, but somehow in a way that makes them interesting.
Trying…and failing, to think of a good portmanteau of interesting and ugly.
Edit: intugly? Ugteresting?
“Striking” is usually the word. It can be used for bad looks as well as good.
Well, as with all my attempts to shine…this has crashed and burned. And not even gloriously…
I actually just tried looking that up, to see if such a word actually exists in English. I found a stack exchange thread asking this same question but no one had a suitable answer. So, yeah, I guess it’s up to you to contribute to society by inventing and popularizing this new word. Enjoy your new destiny.
I guess this is technically the opposite of what you are trying to convey, but your comment reminded me of a song I haven’t thought about in a decade
