A crikey is an expression used to show surprise or excitement.
When someone hears some amazing news, sees something incredible, or experiences something totally unexpected, they might say "crikey" out loud. It's a casual way to react and get their friends' attention, like saying "wow" or "whoa", but with a bit more Aussie flair - Australians often use it as a slang word. You might hear it in everyday conversations when someone stumbles upon something cool on the internet, meets an amazing person, or gets an incredible opportunity.
(UK, Ireland, Australia, Commonwealth) An exclamation of astonishment.
Example: Crikey, mate, that ain't a knife, this is a knife!
