This phrase was made famous in Australia in the 1970's-80's. Over time it has come to mean a knock out punch.

The term was created to describe I blindside punch. Thrown from behind, it is usually a knock out punch not seen coming.

Media has misused the word as any K.O. or massive blow to the head.
-"Kimbo got knocked out!"

'What? How'd that happen?'

-"The bastard KING HIT 'Im."

'Dog Act We'll fix him.'

A colloquial, jazzed up way of saying someone was punched in the head with the intent of the perpetrator being to knock them out.

A word the Australian media is known for overusing as a buzzword, similar to how the media in the US kept calling a recent trend of innocent people being assaulted with a punch to the head "the knockout game".
