Both ... I've even been known to say "Soda Pop"! 🤔
Soda. Definitely! Pop reminds me of an old old old man named Pop refering to his soda as pop! 😅
I call it soda or Coke, I don't think I've ever called it pop.
Usually, I use the name of the drink itself---Dr. Pepper, 7-UP, or (occasionally) Ginger Ale.
But never "pop."
i call it, a hangover the next morning.
I usually say coke or sprite. But it’s soda in the South. The first time I heard someone talking about pop, I just to ask what are you talking about. Never heard pop before or since.
I have always called it soda, but my sister-in-law calls it pop. I have had a friend or two call it Coke, even though they meant soda in general.
I call it soda now . When I was younger I called it pop. Not sure when or why that changed.
