Wait, what?

Back east in June, picked up this phrase from my 17 year old nephew: "Wait, what?" It wasn't something I'd ever heard out hear on the West Coast.

Well, you know it's becoming ubiquitous when it appears in The New York Times (in a tidbit item today about the TV show "Mad Men").

Googling it came up with this interesting "Language Log" blogpost.

I'm hoping for a fuller etymological analysis in the "On Language" column in the Sunday New York Times Magazine soon!
