"geg in" means to intrude; butt or muscle in ; to be nosy. 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
"geg in" is informal English meaning to intrude; butt or muscle in ; to be nosy. It is mainly heard in British English (and Irish English). A more formal or neutral equivalent would be something like "to intrude" expressed in standard vocabulary. A common mistake is to assume "geg in" 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.

“The 12 poets must have a connection to the regional dialect they are tackling: Cumbrian-born Katie Hale is taking on “to twine”, or complain; Liverpudlian Chris McCabe “to geg in”, or butt in, for Merseyside; and Dean Wilson a “didlum”, or community savings scheme, for Humberside.”

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.
