What's the most ridiculous superstitions you've heard from your mum?

Mine was if lady's panties are washed using washing machine, the whole family will be bankrupt because women have menses, and menses blood is dirty. So everybody uses the washing machine and it will affect the men's luck in the household. Even when you're pregnant, you're supposed to squat down and wash your panties yourself because everybody uses the sink, and that will affect the luck as well. #superstitions #randomtalk
