Am I a laughing stock?

Totally this. Some people are happy and joyful and fun and others have to find the fault and negativity in everything. Don't let grumpy people dull your sparkle.

Agree with this post completely. Sister sounds spiteful. Is she jealous? Your house nicer than hers?

I think you sound like a welcoming, warm and fun person and I’d love to be invited to your gatherings if I knew you. Some people are joyless and mean. Keep being you.

Is the reference Fawlty Towers? Implying you’re all a bit wacky? That’s so old now people are more likely to think of Trump Tower. Or is it funny because your house is small?

It is cringey in the same way that people giving themselves a nickname is cringey; like call me crazy carol because I’m so much fun. Just be grateful they’ve humoured you for so long. They are obviously very fond of you to go along with it.

It was probably funny at first, but people have found it a bit irritating when it’s gone on too long. Your sister could have told
you gently though. She sounds pretty horrible.

I think it is fun and makes you an authentic individual. What a sad load of people you must have around you?!

I think you sound lovely and likeable - it’s just a bit of self deprecating humour and along the lines of people naming their cat The Professor.

Your sister comes across as a bit mean tbh in this example

I think your sister was mean, it was just a light-hearted joke and they've made you feel silly. You sound lovely. Don't let other miserable gits bring you down.

I don't see the problem, I actually think your mum and sister went about telling u in a spiteful bitchy ,laughing st you way.
We used to call my mum the countess of (name of village)
Cos in a loveable harmless way she thought she was posh!!
I think it was because she came from a very poor family and our big house,stables fields etc was a far cry from where she began as a child living in a prefab in Sheffield, but she never talked down to people thank god,my pet hate.
Anyhow I've digressed, your mum.and sister sound vile btw

I think you need to change the name to 'Dun Hostin'.

Wow, are you the spiteful sister? As if OP doesn't feel bad enough and you decide to assassinate her entire character. That says far more about you than OP. Nice work - not. 🙄

I've just remembered when we were students we called our house Hawaii Five-O House followed by street address when we were setting up utilities and registering at university etc. We didn't make a sign but only because we were lazy. Friends used it to send letters (remember them?) to us. All harmless fun.

Oh no! I do the same thing!

My friend names her house this too.
I don't have an issue with it. It's just a 3 bed, normal terrace house.
Who cares. Call it what you want

Ooh I think I may know you Op, or at least I have friends who do something very similar to you.
It’s never occurred to me to be irritated or laugh at them? It’s just one of their small quirks.
The strong reaction from your sister though does suggest that other people find it a bit pretentious.

Our house has a name rather than a number, it always has had, we didn't name it and if I were to send written invitations they would say "You are invited to dinner at The White House" (it's not actually called that) and that would be fine I think. If I were to text anyone I would say "10am, our house" instead. I wouldn't use the name of the house in anything other than a written formal invitation or when telling people our address.

I think what you've done is completely fine, it's an innocuous joke and who cares? Your mum and sister are being mean. And I bet your friends just don't care at all but you put one on the spot by calling her and so she had to think about it. I'm sorry they all upset you though, you haven't done anything terrible, not at all so try to forget it and move on.

It is cringy, sorry OP. But I’d be really sad about people taking the piss out of me behind my back. People in this world are so often mean and quick to use their collective power to belittle someone else.

Have you ever asked your friends why they call you this?

Not to derail, but I'm now randomly chuckling at the address for Richie and Eddie's flat in Bottom - which was on Mafeking Terrace!

We have a longstanding group of friends who refer to us as Lord and Lady D (surname begins with D), and I'm always referred to as Lady D within that circle. They also often call our house 'Surname' Towers. However, I've never referred to myself as Lady D nor called my house D Towers. I do refer to DH as 'his Lordship' on occasion, eg. "I'll have to check with his Lordship and let you know" kind of thing, so I'm not completely averse to a bit of faux pretention! However, I'd feel a bit cringe calling my house Dxxxx Towers, or myself Lady D. Fine for others to do so in a jokey way, but I'd feel self conscious using those epithets myself.

But each to their own, and if you like it and want to continue using it then style it out and crack on. The world would be a very dull place if we all stripped ourselves of any personality for fear of annoying others.

I think it’s funny, and if you were my friend I would have really enjoyed gently laughing about it a bit behind your back. It would have enhanced my life slightly.

BUT my priority would be our friendship and I would never let on that I found it cringy, I would be mortified if I hurt your feelings.

Is there anything your friends do that you find secretly a bit funny but would never let on? I hope so, how boring would life be if we were all the same and all liked the same stuff and weren’t allowed to do things we think are funny.

It's harmless and it wouldn't bother me. Is your sister maybe jealous you have a bigger house than her? They sound bitchy to be mocking you behind your back.

I think it's quite funny

Personally I would just accept that this was just part of who you are.
It wouldn't bother me in the least if that's how you choose to refer to your home.
It's just a quirk and people are entitled to having harmless quirks.

Your sister sounds as though she has other issues with you and she decided to settle on this to " bring you down" . It was spiteful and unpleasant of her.

And I would suggest anyone else who criticises you over this should get a life - an expression I dislike and rarely use but which seems appropriate in this case.

I should have said, you’re not a laughing stock though.

The other option I guess is to lean into it and do it more, as some pps have said.
