Fibbie is American slang for an FBI agent. Used in crime drama and casual conversation. Not concerning, just slang. 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
Fibbie is American English slang for an FBI agent. Use in casual contexts and crime-fiction writing. Formal equivalent: "FBI agent." Common non-native mistake: pluralisation; both "fibbies" and "fibbie's" appear. Standard plural is "fibbies." Often used in police-procedural fiction. 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.
