Fine, fine...fine... (In mocking tones if anybody in my family says "fine" with attitude!)
I really dislike that "fine" crap. And the Southern version: "that's fine"; equally aggravating.
If you're mad, just frickin say so.
Yeah...I usually go..."OK, _________ is really pissing me off!", pretty ambiguous, eh?
My sister will lead with the f-bomb often, I may only throw that in between "really" and "pissing" depending how vexed I may be. Funny my big bro often whips the "fine" out there the most...and hence gets lit up the most.
The other one we like to whip out there when somebody is struggling with something is "use your words" like they are a toddler...that usually provokes a response.
