club soda

Club soda is plain carbonated water, often with added minerals. Standard beverage vocabulary. Not concerning. If your kid uses it constantly, ask them where they first heard it, not to police their speech but to understand which online community they are in. Most slang of this kind moves through TikTok and group chats, so seeing it in your child's vocabulary just means they are plugged into normal teen internet culture.

Club soda is a carbonated water beverage, typically with small amounts of added sodium-based minerals for taste. Use in food and beverage writing. Formal equivalent: "carbonated water with added minerals." Common non-native mistake: confusing with seltzer (pure carbonated water) or tonic water (carbonated water with quinine). Each is distinct in composition. Read or listen to the word in context several times before trying it yourself; the right register is harder to learn than the dictionary meaning.
