giggler

noun

1. A person who giggles, or an inanimate object that can emanate laughter.

   “Band concert public square Nebraska city. Flowing and circling dresses, summer-white dresses. Faces, flesh tints flung like sprays of cherry blossoms. And gigglers, God knows, gigglers, rivaling the pony whinnies of the Livery Stable Blues.”

   “She was not a giggler, despite her extreme youth, and she smiled the small slow smile that men brought to her face without knowing why.”
