Explanation

  • British informal adjective meaning utterly astonished, speechless, or amazed.
  • Implies being so surprised that your mouth hangs open (gob is UK slang for mouth).

Origin

  • Combination of gob (slang for mouth, possibly Celtic origin) and smack (to hit).
  • The image is of being metaphorically smacked in the mouth, leaving you speechless with surprise.
  • Emerged in the UK around the mid-20th century.

Alternatives

Slang/Informal:

  • Floored (Meaning: Knocked over by surprise)
  • Mind=blown (Online/Meme culture)
  • Shook (Newer slang, esp. online) (Meaning: Visibly shaken by surprise/emotion)

Vulgar/Emphatic:

  • Fucking amazed / Fucking stunned
  • Holy shit! / Holy fuck! (Exclamations of shock)

Milder/More Formal:

  • Utterly astonished.
  • Quite surprised.
  • Left speechless.

Situational Appropriateness

  • Informal. Very common in the UK and increasingly understood elsewhere due to media.
  • Fine in casual conversation among friends, family, colleagues.
  • Avoid in very formal settings where astonished or surprised would be better.

Misunderstanding Warnings

  • The main risk is non-comprehension outside regions where it's common.
  • Non-native speakers need to learn it's a strong expression of surprise, not related to physical violence despite smack.

Examples
