A sly and filthy prank whereas someone runs into a laundromat and takes a quick dump into a washer filled with someone’s clothes and then tears out before anyone can stop them.
We used to get seriouslydrunk and then go laundromat turding before calling it a night and going home!
it is important that you choose your laundromat carefully especially if you are going to wash sth valuable; in a good laundromat, for example, you can adjust the speed of washing (in case of delicate stuff you should rather use low speed: then it will not be damaged and still clean eventually)
Look there, I really like this laundromat! Let's go for it: it looks like the quality is high and it has many functions.
