noun

1. (countable, uncountable)Impish or playful behaviour; mischief.

   “I yield to no one in my appreciation of her espieglerie, but I'm one of the rabbits and always have been while she is about as pronounced a dasher as ever dashed. What I like is the quiet life, and Roberta Wickham wouldn't recognize the quiet life if you brought it to her on a plate with watercress round it. She's all for not letting the sun go down without having started something calculated to stagger humanity.”
