Fizzoddity

A odd, and probably disgusting concoction of different sodas.

Friend: "I came up with a new fizzoddity!"
You: "What is a fizzoddity??"
Friend: "Basically, I made a disgusting combo of sodas, Sprite, Root Beer, and Coca Cola. It probably tastes like the worst thing known to man, but that's a fizzoddity for you!"
You: "Gross."
