chatter
This word carries a light, airy, and often superficial energy. It suggests a lack of depth or seriousness, evoking the image of birds chirping or people gossiping without a specific goal. Because of this, it can be used affectionately to describe lively social energy or pejoratively to describe annoying, pointless noise.
Countable when referring to a specific instance of a conversation or a burst of noise. Uncountable when referring to the general quality of rapid, trivial talking.
