(US, military slang) lieutenant junior grade.
"jaygee" means lieutenant junior grade. 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.

"jaygee" is informal English meaning lieutenant junior grade. It is mainly used in North American English. A more formal or neutral equivalent would be something like "lieutenant junior grade" expressed in standard vocabulary. A common mistake is to assume "jaygee" can replace its standard equivalent in every register; keep it for spoken or casual situations and use the formal form in writing. 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.
