What it means
A blunt little brush-off that means no chance, do one, or piss off in the polite-clothes version. It’s rude, sharp, and very British, but it stops just short of full nuclear swearing. You use it when someone’s being cheeky, pushy, or taking the absolute mick. Said with a smile, it lands even harder.
Usage examples
"Manager pings at 9pm asking you to just jump on a quick call. Get stuffed, I’m in my pyjamas, mate. Ask someone else."
"He asked me to work yet another Sunday for free, so I told him to get stuffed."
"Get stuffed, you're not having the last slice after you ate the whole rest of the pizza."
"She tried to jump the queue then got lippy when I called her on it. I just said get stuffed and carried on."
"If they think I'm paying fifty quid for warm prosecco and a sad mini burger, they can get stuffed."
Where it comes from
This has been kicking around in British English since at least the 1950s as a softer stand-in for harsher send-offs. The punch comes from the euphemism. Instead of going full swear-cannon, you tell someone to get stuffed, which still carries that same door-slam energy without dropping the strongest version.
