Explanation

  • To make a mistake, especially a careless or significant one; to mishandle or ruin something.
  • Can also be used as a noun (a screw-up) to refer to the mistake itself or the person who made it.

Origin

  • Emerged in American English around the mid-20th century.
  • The verb screw has various mechanical meanings, but its use in slang often carries negative connotations (e.g., screwy meaning odd, getting screwed meaning being cheated).
  • Screw up likely evolved from this general negative sense to mean mishandle, tangle, or mess up badly.

Alternatives

Slang/Informal:

  • Fuck up. (Vulgar, much stronger emphasis on the severity or carelessness of the mistake)
  • Cock up. (UK/Aus informal, mildly vulgar)
  • Bollocks up. (UK vulgar)
  • Flub. (Make a minor error, often in speaking or performing)

Vulgar/Emphatic:

  • Fuck up. / Fuckup (noun)
  • Shit the bed. (Very vulgar, implies a complete and embarrassing failure)

Milder/Standard:

  • Make an error.
  • Get it wrong.
  • Miscalculate. / Misjudge.
  • Err. (Formal)

Situational Appropriateness

  • Informal.
  • Generally too informal for formal business reports, communication with clients, or addressing high-level superiors unless the relationship is unusually casual.
  • Mess up is a slightly safer informal alternative. Fuck up is vulgar and inappropriate for most professional contexts.

Misunderstanding Warnings

  • The literal meaning involves turning a screw. While context usually makes the mistake meaning clear, ensure learners understand it's figurative and informal/negative.

Examples

  • I completely screwed up the recipe, and the cake turned out terrible.
  • He screwed up his interview by arriving late.
