New Age traveller

"New Age traveller" means a member of a community of people, many of whom hold new age beliefs, who travel among fairs and music festivals. 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.

"New Age traveller" is informal English meaning a member of a community of people, many of whom hold new age beliefs, who travel among fairs and music festivals. It is mainly heard in British English (and Irish English). A more formal or neutral equivalent would be something like "a member of a community of people" expressed in standard vocabulary. A common mistake is to assume "New Age traveller" can replace its standard equivalent in every register; keep it for spoken or casual situations and use the formal form in writing.
