“Dink” has a few slang meanings, and the right one depends on context. The most common are: a mild insult for a silly or annoying person, a term for a couple with two incomes and no children, and in some sports, a soft, delicate shot.

Common meanings

  • Insult: a dumb, annoying, or contemptible person.
  • Financial slang: “double income, no kids” or “dual income, no kids.”
  • Sports term: a light, soft hit or shot, especially in tennis, volleyball, or pickleball.

Important caution

  • In some older or regional uses, dink has been used as a derogatory ethnic slur, so context matters a lot.

Example

  • “Stop being such a dink” usually means “stop being annoying.”
  • “They’re a DINK couple” means they have two incomes and no kids.
