(aviation) The fuel that powers a jet aircraft.
"jet fuel" means the fuel that powers a jet aircraft. 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.
"jet fuel" is informal English meaning the fuel that powers a jet aircraft. It is used widely across English varieties. A more formal or neutral equivalent would be something like "the fuel that powers a jet aircraft" expressed in standard vocabulary. A common mistake is to assume "jet fuel" 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.
