How to say "brat" in Japanese

• 悪童あくどうCommon
  nounCovers the mischievous sense of brat: a naughty child who plays up and causes trouble. The emphasis falls on the child's bad behaviour rather than on age or status.
• 小僧こぞうCommon
  nounUsed of a boy, it is a scornful, dismissive way to say 'kid' or 'brat' — what you might call some young boy you look on with contempt.

  Are you going to play tricks on me again, you naughty boy?
