Seinfeld of course didn’t coin the word “hand”, but I think they were the first to use it in the sense of “moral superiority”. IIRC, George described an argument with his girlfriend: "I have the upper hand! I have HAND!
Don’t know how many people use it in that way, but I do. On those rare occasions that I possess it over my wife.
@Cheesesteak: Ref @RivkahChaya’s comments a bit above, how old was the person who first said it?
ISTM there’s the kids of the 1960s who learned it first hand (like me), the 1970s & 80s kids who got it from syndication, and the 90s or later kids who got it from parents, or the culture at large.
The really cool thing about that is that Batman aired two nights in a row. Wonder why so many shows were two-parters? The first night’s show always ended with a cliff-hanger… "IS it darkest just before the dawn? Tune in tomorrow, same bat time, same bat channel!"
And why was Batman on two consecutive nights? The producers envisioned Batman as a one-hour TV series. However, the network, ABC, moved the premiere from its original fall 1966 airdate to January, 1966. They didn’t have a one hour slot available on their schedule, so they cleared a half hour on Wednesday and Thursday nights instead. The movie was supposed to serve as an introduction to the series, but due to the change in schedule, was produced at the end of the first season.
I would argue it’s only a good name, though, if the original meaning is no longer in use. Otherwise they’d run into the problem where, if someone talks about needing unobtanium for their project, you can’t be sure if they mean the Pandoran material or just something that’s perfect or hard to be obtain.
It would be like naming your new your new product “Stuff.”
