assage

"assage" is sexual slang. In short, it refers to ass, in the sense of buttocks, and in related idioms. 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.

"assage" is informal English meaning ass, in the sense of buttocks, and in related idioms. It is used widely across English varieties. A more formal or neutral equivalent would be something like "ass" expressed in standard vocabulary. A common mistake is to assume "assage" 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.
