Nattery

She was a maddening person from whom you would flee if you met her in real life: a nattery, chattery, high-strung, high-flown bundle of pretensions with a lot of Ancient Mariner in her. But on the screen, a delight.

Some people can indeed do much of their narrating in a nattery manner, verbalizing whatever pops into their heads in the same basic disorder. Chatterboxes, we call them: motor-mouths.

A “nattery party,” was an officers' meeting or conference during which there was far too much talking that usually resulted in little action.
