bagatelle (bag-uh-TEL) noun

1. Something unimportant.

2. A kind of pinball game in which balls are struck with a cue to send
them to holes at the other end.

3. A short, light piece of verse of music

I had always heard the term to mean also a motley collection of anything

But I had never heard def 3 above. Does anyone know its approximate age, or is it a neologism

Thanks all
