Yes, it is extremely rude, inappropriate, and unsanitary to poop in a washing machine. Washing machines are designed for cleaning clothes, not for disposing of waste. Doing such an act can damage the machine, spread germs, and create a significant mess. Additionally, it would inconvenience others who rely on the washing machine for its intended purpose.
If you have a waste that needs disposal, always use a proper toilet or restroom facility. Respect public or shared spaces and ensure you follow basic hygiene and etiquette guidelines. Deliberate misuse of appliances or facilities is not only disrespectful but may also be subject to legal consequences in some cases. Always use facilities for their intended purpose and be considerate of others sharing the same spaces.
