Yeah i'm an early millenial and i got in trouble as a kid at a trading card game convention because i was playing the x files card game, which involved asking the other player yes/no questions and the guy demoing the game mistook my no buzzer noise for a yes buzzer noise and lost because of it.

About 6 years ago we were sitting on the beach and a larger wave came in out of nowhere that went say 20-25 feet further up the beach to where we were sitting, I grabbed her and my phone and said ruh-roh as she realized and stood up, didn't have time to grab the small Bluetooth speaker we had and it got soaked and I grabbed it a few seconds after as the wave retreated. It isn't a term I say often, but I think it was something I did back in my early twenties when there was the possibility of kids being around. Instead of yelling "oh shit" my 37 year old brain decides to sound like a cartoon dog.

I think "ruh roh" is far older than gen Z. I think the first time I ever heard it was a gen X'er. Maybe it just got more popular?
