Quick, blunt way to tell someone to go away, stop pestering you, or drop a stupid idea. It’s got that fake-polite vibe, like you’re suggesting they take a little run, but it’s still a proper brush-off. Works for randoms in the street, pushy sales types, or even your mate when they’re chatting nonsense. Tone depends on delivery.
"Bloke kept chatting bare rubbish on the Night Tube, leaning in like we’re pals. I just looked up and went jog on, mate, and he moved down the carriage."
