What it means
Being mildly annoyed or a bit put out, usually with that restrained, polite simmer rather than full-on rage. You’re not kicking off, you’re just quietly judging and you will a hundred percent bring it up later over a brew. Can also mean a little offended, especially when someone’s been rude without even noticing. Slightly old-school and a touch posh.
Usage examples
"I’m proper miffed they started the pub quiz without me. I was in the loo thirty seconds, mate, and now Dave’s nicked my seat."
"She was a bit miffed she did not get an invite, but she would never say so out loud, just go quiet."
"I was miffed they changed the meeting time and did not tell me, so I turned up to an empty room."
Where it comes from
Built on the old word miff, an eighteenth century term for a little fit of bad temper or a tiff, probably born from the huffy sound you make when you are put out. To be miffed is to be in a miff, quietly ruffled rather than truly raging.
