Yeah, I see how they slot in now with the whole Ed "Big Daddy" Roth Weird-Ohs craze (circa 1969). There's a cringey "Leave it to Beaver" TV episode whose existence shows the cultural impact the "weird ohs" had on suburban norms (Beaver and his boy-pals each have a weird-oh shirt they agree to all wear to school on the same day ... well, you can guess how that plays out).
I think it instead that is a fascinating example of how complex humans and societies are. You could write dozens of books on the subject and still not fully explain one weird thing we do
