Genius Is…

One that wasn't included on the list (because it's a word and not a phrase) is the word faze. As in, "That didn't faze her a bit, so she kept going." When I was a kid, I heard it in a song and asked my mother about it. She explained the meaning, and told me it was pretty much archaic and very rarely used in modern language. Fifty years later, it seems everyone on the internet is using the term with the correct meaning, but they spell it "phase."
