A buttery crumpet?
UKCasual
A friendly place to chat.
No politics please. Don't be a dick.
Mmmm

How about this most British of pictures? Angry person, reactolite glasses, a sausage ready for the back garden barbecue and even a sneaky garden fence. If there was a wheelie bin in there it would cover 90% of normal chat :-)
(Edit: and please for the love of all that is holy do not use a top-hat or a monocle. Those are lazy parodies of Britishness used mainly by Americans whose idea of the UK comes from The Crown and Downton Abbey. There's only one person who I can even imagine wearing either item regularly and I would probably get banned for saying what I think of him.)
Lemming wearing a top hat and monicle. Drinking a cuppa
How about a lemming sipping tea like the Kermit the frog meme?
Something like this?

Love it.
This is brilliant! How'd you come up with it so quickly?
AI, innit.
Bruv I tried AI and got this, not quite the same lol

And yet so charming in its way!
I honestly prefer yours. It's adorable!
Oh thanks! Well seems like there might be a couple of options then 😊
this is the best :-)
This was my go, love how we're all getting totally different styles!

This one is great! I love how gentlemanly he is
He's a dapper chap isn't he
Looks lime a winner to me.
Maybe more suited to UKFormal?
I actually love this.. lemming in bowler hat sat in a cup of tea.. very british
What a dapper fella
Is that AI?
An imposing picture of Mr Blobby
So, just a picture of Mr. Blobby?
Honestly that diseased penis looking fucker haunts my nightmares.
The Alonso Deckchair image with the Union Flag as the background. Also give Alonso a Top Hat plus Monacle
I was always fond of this image, but am loving the lemming top hat.

Spotted dick and tea.
America gets gun and hamburders.
India gets many phone icons.
Australia gets scary spider on a dingo.
Just for fun I asked gpt-4 what the most British thing is, I then asked it to make a prompt for midjourney. Here is the result. (Don't question the alien hand)

Ugh the hands. Always the hands.
Never forget that the classic video game Lemmings is itself a British creation.
This would be my pitch:

Alternate version and transparent PNG
Still an official™️ Lemmings skin tone, but one from a later game I guess, in the interest of inclusivity:

Transparent PNG in case anyone wants to remix it:
Easy, relevant banner idea
Use a screenshot like this one, but decide what they're queueing for. Greggs? Woolies? Half-price biscuits? The possibilities are endless.
Gotta be between this and top hat lemming. Does Lemmy do polls, yet? 🤔
Ooh, I love it! I'm inclined to go with the banner already. Any objections?
Make it so (please)
This has got to be it, it's perfect
I now think a duck would be the funniest. Obviously, the ultimate "middle-finger" to the old regime.

Greggs pasty, or a nice cuppa (pending inevitable bickering over exactly what shade of tea)
Edit: Differentiate ourselves from the other place with an icon of a duck
I was thinking something Greggs based as well. I was just going to say the logo though 😂
I was thinking something Greggs based as well
I know this is a safe space, so I'm going to say something controversial. I don't like anything Greggs make (apart from the jammie dodger biscuit)
... There's a limit to how safe a space gets you know
Yeah, that's fair. I'll take it on the chin!
What's your local alternative? There's a chain in the North-West called Greenhalch's that's solid, or Cooplands in the Midlands is good too.
We have Parsons which is OK. Plenty of independent bakeries but all quite expensive (think £2.60 for a plain croissant). I don't tend to bother.
A quick image search for "union jack rubber duck" shows some contenders...
I approve of duck. Everyone likes duck
A deckchair? A pub sign?
A pubsign for a pub called The Deckchair?

I propose this cute rubber ducky! All hail the duckies!
