i'm a soda boi I like combining them both and calling it a sodie-pop like h3h3. I call Schweppes, Schweppays
Here in the UK, we call it coke - even if we mean a Dr. Pepper, Pepsi, Sprite, Fanta, anything. Kinda like how we call vacuum cleaners 'Hoovers', despite being far more likely to own a Dyson or something than a Hoover. Alternatively, 'fizzy drink' works too. Neither.
I say neither, but we've been through this quite enough already, I think. https://empireminecraft.com/threads/soda-vs-pop.67645/
You are forgetting about another way asking for soda which I still used daily cause grill into my head. Coke Example: "Would you like a Coke?" "Yes I would" "What kind? Dr.Pepper, Coke or Sprite?" "Dr.Pepper, please." Mainly a Texan thing for most part and a few Southern States. lol
I usually just say whatever I'm thinking about... Dr. Pepper, coke, etc, is not often I have to refer to them collectively... But when I do, soda.
