This colostomy bag was BANNED for his toxic body odor. You can help by learning from his mistakes of not using deodorant or bathing regularly. Maintaining a safe distance or wearing a gas mask whenever he's around would also be in your best interest.
This odorous, scent-driven rat is proud to divulge he doesn't use deodorant, body soap, shampoo, cologne, laundry detergent, or toothpaste irl. Artificial, factory-produced scents offend his senses, and pheromone detection is his truest indicator of attraction.
Water is nature's shower, and is all you need in order to stay clean and maintain good hygiene, and to of course enable your body to naturally produce innocuous body odor, which this user has a strong admiration for.
