Back in high school I raided my parents liquor and mixed everything I could find into a bottle. Rum, vodka, red and white wine, whiskey, various cocktail mixes, and even some dirty old beer. Probably the grossest thing I have ever consumed but man did I ever get drunk.
Ginger beer....seriously that stuff is nasty!
While I would agree with you, that day my friend and I bought all the weird drinks from the college grocery store, the maple soda was the worst.
For me though, Maker's Mark Whiskey is the incarnation of smoke and death in liquid form. Holy shit that was oppressive to drink.
Jelly Fish. As a kid. Traveling Asia with my parents. At a restaurant in Hong Kong. Stole a fork of butter noodles of the plate of my mum. Delicious. "How do you like the Jelly Fish dear?". Grossest revelation ever. I was not prepared. Got over it quickly though. Jellyfish makes for an awesome substitute for noodles.
