nancy

"nancy" is sexual slang. In short, it refers to an effeminate man, especially a homosexual. Among teens it is usually used jokingly, as crude banter, or in TikTok-style algospeak rather than as a serious statement of behaviour. Persistent or aggressive use directed at a specific person, especially online, is the bit worth paying attention to: that can shade into harassment. If you hear it once in a chat with friends, it is probably nothing. Repeated targeted use deserves a conversation about respect.

"nancy" is highly informal and vulgar English meaning an effeminate man, especially a homosexual. It is mainly heard in British English (and Irish English). A more formal or neutral equivalent would be something like "an effeminate man" expressed in standard vocabulary. A common mistake for non-native speakers is to use "nancy" thinking it is neutral; in fact it is rude and can offend, so avoid it in writing or in any professional setting. 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.
