In recent many months/couple years? I've noticed this phrase come into pretty wide use: "Yeah, no." I've even caught myself using it completely naturally, without thinking about it.
When and how did this phrase come into our regular usage?
Couldn't say when that verbal tic came to the fore, but I have long had that habit of prefacing almost everything I say with 'No, ...' even if it wasn't a yes/no question.
Interesting article, but the author's Google-fu is extremely weak. In less than 5 minutes I was able to find these two uses that predates his earliest find (1997):
I've used it before, mostly when someone makes an utterly asinine suggestion. My polite response would usually be something saying that, while it is an option, it's idiotic and here's why, so "Yeah, no" is just a shortening of that. It does sound like something from a '90s sitcom, so I would guess that as the origin.
