A Futurama reference, cool, I had to look it up, and apparently it's similar to Surge soda which was introduced in '97,

Surge tastes like a cross between Sprite and Mountain Dew.

i assumed, with the whole "source of the slurm" episode that it would taste something like a sweet with a bite carbonated milk or syrup.

Yeah but some things don’t taste like you’d expect- eg you’d expect cow’s milk to taste like grass but to me it just tastes “white”
:O
