Sitting...

[moltopianissimo]

...is a word.

Please use it! (See also "standing".)

I'm not British, but I know immediately who is, accent or not - the minute the word "sat" or "stood" or "floor" (for ground) is used instead of sitting, standing and ground.

If a person was sat, to me it means that someone else placed them there on the seat, same for stood. And ground is the ground, not the wooden floor in your living room!

Me neither.
I always say talk how you want.

I dont say either.
I normally say I'll park my arse here.

as dd reminds me, language evolves

It's taken about 5 minutes of deep thought to realise you are completely correct. To be sat isn't a verb re something you do yourself, it's something someone does to you

Ding realisation dawns for Scarf

although Romesh Ranganathan just said this very phrase "sat right opposite me"

And its lose not loose by the way 😁
see this everywhere and it makes me mad

The use of loose instead of lose, is often an autocorrect I'd say, well I hope so!

Nah, I’ve seen it loads of times at work in emails and written.

Ugh, I hate “I was sat” it sounds awful

YANBU

“She sat right opposite me” would be fine, though. It’s “She was sat right opposite me” that’s the problem.

he was talking about somebody who is Sat right opposite me
indeed a problem

This was drummed into me as a child and always irritates me! As my Grandfather always said; ‘you wouldn’t say “I was ran” instead of “I was running” would you?’ “Sat” is the same form of past tense
