What it means
To bin off something is to ditch it, cancel it, or drop it because you can't be bothered, you've had enough, or a better option's turned up. You can bin off plans, jobs, messages, even people. It's blunt, a bit cold if it's about a person, and very UK in the way it sounds casually ruthless.
Usage examples
"We binned off the gym and went to the pub instead, best decision we made all week if I am honest."
"It was raining so we binned off the hike and went to the pub instead."
"I was meant to go on that date, but I binned it off after he started sending voice notes at 2 a.m."
"We binned off the group project meeting and just did it over FaceTime later."
"Honestly, I binned off cooking and got a kebab on the way home."
Where it comes from
It comes from bin, meaning a rubbish bin or trash can. In British English, if you bin something, you throw it away. Bin off grew from that same image, turning ditching a plan, task, or person into this neat little picture of chucking it straight in the bin and moving on.
