"FAA" means (9 usc 1). It is one of many casual words teens pick up from friends, social media, music or sport, and on its own it carries no particular warning. If you hear your teen use it, it is fair to ask what they mean by it in their friend group, since meanings drift quickly. Asking out of curiosity rather than alarm tends to keep the conversation open and useful.

For ESL learners
"FAA" is formal / specialist English meaning (9 usc 1). It is used widely across English varieties. A more formal or neutral equivalent would be something like "(9 usc 1)" expressed in standard vocabulary. A common mistake is to use "FAA" in casual speech where a simpler phrase would do; reserve it for formal, technical or written contexts. If you are a B2 or C1 learner, it is useful to recognise this word when you hear or read it, but think carefully about whether the situation really calls for it before using it yourself.

Why is this section here?
Slang is read by different audiences for very different reasons. The For parents view re-explains the term in plain, non-judgemental language so a caregiver can understand what their child means without needing the surrounding subculture. The For English learners view focuses on register (when it's safe to use), formal alternatives, and common mistakes — what a textbook won't teach you.
