look up any word, like sex:
An intoxicating mixture of Malibu Rum and Stella Artois, usually drunk 2 part Malibu to 1 part Stella. Stellabu came to being by chance, but has long prevailed as the drink of choice 'South of the river'. When mixer just isn't available, and you see some Stella lying around, you know what to do.
Person 1: "Why are you hanging off a tree?"
Person 2: "Stellabu"
