Help me annoy our neighbours

Leave the house for the day starting from 5am on Saturday and leave music on full blast.

So many inventive suggestions.
My friend years ago told me a story about her friend who had very loud annoying neighbours when she was renting as a student and they got into the habbit of throwing bird seed into their back and front garden and on their car.
She was an early riser and the noise was something else combined with bird mess on the car. Gave them a great laugh.
They also stuck a small potato in the exhaust of the car.
Stops it dead, but doesn't do any harm.

Maybe they can hear you too, if the walls are so thin?

Schadenfreude doesn't normally invole setting someone up.

Focus on dealing with the actual issue, the noise, and not how friendly they are (neighbours don't have to interact) or speculation on how they pay for their car (who cares if it's on finance or not, it's none of your business). Environmental Health at your local council would be the place to start.

I’m living with them now. And quite frankly it’s a lot worse than this nonsense. They don’t say hello, own their house lease a car and squeal.

Disgusting but...wee in a bucket for a couple of days, keep it outside in a shed or covered up, as it'll soon start to stink of fish, then pour it on their doorstep in the middle of the night.

Or you could tip it out next to the drivers side of their car if you don't want to go near their property.

Deleted as oddly posted twice.

Dear god, I would ignore you as well.
You clearly despise them and their car ( does anybody really say nouveau riche), so why on earth would you give or want a friendly wave or hello from people you disapprove of?

They sound appalling, OP.
We have endured dickhead neighbours, so I feel your pain.

They squeal constantly?? Ok.

op, do you have a job? Something to focus on rather than your neighbours?

My neighbor plays darts and his board is attached to the wall that adjoins our house.

When he decides to have his very regular practice session, i hear three loud thuds repeated every 45 seconds for an hour or 2 at a time.

It's slowly driving me insane . So i recommend you and dd take up darts.

Op you're the problem here.

Buy some black electrical tape then "alter" the rear number plate on their car. Be sure to make it look obvious so it will draw attention and get them pulled over.

A lovely paste of weetabix and milk left to dry on a hot day on the bonnet of the car 🥸

OOh I had sucky neighbors for a many years, they just moved so I consider it a win. I put my compost bin right next to my fence but about a foot from their deck, stuff stinks in the summer here and dam, the flies it attracts. I had a mate, who owns a farm, supply me with nice ripe manure for my veggie beds right before their 4th of July cook out, I did this annually and my mate could deliver quickly when I saw the signs of a gathering so I always managed it. I rewilded the ground at the side of my garage, let it go totally wild. I cant see it from my window but its right next to their front yard ans totally noticeable from their front windows and ran the length of the property line. The vines were EVERYWHERE. I had wind chimes everywhere, and bottles of coyote pee.( we have ground hogs and the smell keeps them away) I planted thuja trees and bushes along my property line that took care of any sun hitting their pool deck eventually. Then I got bees.
Nothing illegal but I drove them crazy, these people were awful, used to call the cops on my kids any chance they had, put a bucket truck over my fence and took down 1/2 a tree before I got home and stopped them, called building enforcement every time I had work done even when they could see my permit in the window ( but those same building regs didnt actually apply to them). I was thrilled to bits they moved and Im sure they probably were too as I had made it my mission to be "that" neighbor

What a great idea! I definetely dont have enough imagination!

Can you not complain to the police about the noise?

As for revenge, after a party, they would certainly be sleeping, so its the time for making noise. My sister annoys her upstairs neighboors who listen to Bollywood movies in the middle of the night with loud classic music in the morning.

-Ignore them too.
-Put something sharp where they park their car.
-When you leave, put something close to their door that will rot and stink (someone I know did it to a vile neighboor)
-Use magick (tons of books on amazon), there are spells on quieting loud neighboors or even making them move. I would go with the latter, many people have success with that.

A bloke I knew who worked in a garage once mocked up a number plate with something very rude on it, 'WAN K3R' or something, and stuck it to the rear plate of someone's car. They drove about with it for a couple of days before they even realised.

A few tins of veg every soup over the Range Rover, make it look like someone has puked on it.

Revenge topiary

Their Range Rover (definitely heavily financed) is constantly parked right over the pavement, forcing buggies and wheelchair users onto the busy road
I believe that's the only way a range rover can be parked, other than in a bike lane or straddling two parking bays.
