What it means
A mildly rude way to tell someone to get lost, basically the clean-ish cousin of fuck off. You use it when you're fed up but still trying to keep it TV-friendly. Sounds a bit old-school, which is half the charm. It got a second life after Princess Anne allegedly snapped it at photographers. Short, sharp, and very British.
Usage examples
"He kept leaning over my pint chatting absolute nonsense, so I told him to naff off and went back to the darts."
"Told the cold-caller to naff off and put the phone down."
Where it comes from
Built on "naff", a mild British word for tacky or worthless, popularised as a tidy stand-in for stronger language. To tell someone to naff off is to send them packing without quite swearing, the sort of thing you could get away with on teatime telly.
