Bad parking is on par with aggressively standing on the left on a Tube escalator, drinking out of the milk carton at work and leaving one square of toilet paper.
It wrecks the delicate fabric that holds society together and can turn a perfectly reasonable urbane chap into a seething neanderthal warrior in one careless turn of the steering wheel.
We've all noticed appalling parking, and now, of course, there's an app for that.
Parking Douche, a new app for Android phones, is naming and shaming Moscow's worst parkers and sharing their awful parking attempts with their friends and neighbours online.
When the app is downloaded, users can snap shot of poor parking, upload it to Parking Douche , then the shot gets shared online on The Village, with people near where the shot was taken.
The company can do this by geo-locating IP addresses, embarrassing the shoddy parkers by exposing them to their friends, colleagues or neighbours.
Ads will pop up featuring the douchey parking on Moscow news site The Village.
The app is yet to go global, but parking douches are not exclusive to Moscow. If you've spotted shockingly douchey parking, send them in to us at email@example.com using the hashtag #parkingdouche.
