A fork of Rural Dictionary
When a female stands on her hands or lies on her shoulders with her vagina facing the ceiling; then her partner separates the lips and pours a cocktail of delicious beverages into said vagina, and drinks from it with a straw. Afterwards, the man may fuck the female and have her lick the leftover liquid from his penis. This is called the Mississippi water hose.
