Fuking nurries mate!

I left a little nurry in my dacks.

I'll kick ya in the Nurries.

As opposed to 'No wucken furries' - or No <expletive> worries - which is wrongly attributed to this word.

Usually used in the phrase "No worries, no nurries" during the exchange of similar 'rhyming' insults.
For example
Person 1 - "Cheers, big ears"
Person 2 - "Same goes, big nose"
Person 1 - "No worries, no nurries"
Person 2 - "Who cares, pubic hairs"
Person 1 - "Give a stuff, bum fluff"
Person 2 - "Give a f**k, toilet duck"
