I was at a cookout yesterday and my wife and I were playing Frisbee with a 3-year-old boy. He kept up a running dialogue, and at one point said, "I just got a new car. It's a, it's a Toyota. Toyota. Yeah. Toyota is my favorite sound. It's, ah, it's a Camry." I thought that was great. There are lots of words that are just fun to say out loud. One my wife introduced me to is atlatl. (Listen to it here.) It's a ancient spear-throwing device.
Anyone have any favorite sounding words?
