I learned a new word today: riffing. Apparently, it is a common word of sort although I haven't run into the word until now. Just in case you didn't know either, it means:
- Music. A short rhythmic phrase, especially one that is repeated in improvisation.
- A clever or inventive commentary or remark: “Those little riffs that had seemed to have such sparkle over drinks… look all too embarrassing in cold print” (John Richardson).
