13. Never Toast with Water
In 19th-century Europe, toasting with water was considered unlucky or even rude. This superstition was rooted in maritime folklore, where sailors believed that toasting with water would lead to drowning. The U.S. Navy’s Mess Manual stipulates that toasts are never drunk with liqueurs, soft drinks, or water, as tradition holds that the object of a toast with water will die by drowning (colonialbrewer.com).
