Explanation

  • A command or suggestion telling someone to be less serious, worried, angry, or intense.
  • Encourages someone to relax and not take things so seriously.

Origin

  • Appeared in the early 20th century.
  • Uses the metaphor of physical weight: seriousness, worry, and anger are seen as emotional burdens or heaviness.
  • To lighten up is to reduce this emotional weight, becoming more cheerful or relaxed.

Situational Appropriateness
