“Fluke” usually means something that happens by chance, especially a lucky or unlikely success, not because of skill or planning.

Main meaning

  • A fluke is an unexpected or unusual event that happens by accident, often in a good way.
  • People use it to say something was “just luck,” not proof it can easily happen again.

“That goal was a total fluke” = it went in by luck, not because the player meant it.

Other meanings

The same word also has some more technical meanings in English.

  • A parasitic flatworm (a type of fluke worm) in biology.
  • Either lobe of a whale’s tail.
  • The hooked blade of an anchor that digs into the seabed.

How people use “fluke” now

In everyday and online talk, “fluke” is mostly used for:

  • Lucky wins in sports or games
  • Surprise successes in exams, business, or tests
  • One‑time events people don’t expect to repeat

So if someone asks “Was that a fluke?”, they are asking whether it was just luck rather than something you can reliably do again.
