300 Club refers to bowling a perfect game (300 points), an exclusive achievement. Standard sports 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.

For ESL learners
300 Club is bowling vocabulary referring to bowlers who have rolled a perfect game (300 points, all strikes). Use in bowling and sports writing. Formal equivalent: "perfect-game bowlers." Common non-native mistake: confusing with other "300 clubs" (Air Force aviators, military thresholds). In bowling contexts the meaning is unambiguous. 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.
