The phrase combines kawaii, a widely used Japanese word for cute that is common in anime and internet culture, with ta mere, informal French slang for your mother used as a teasing insult. The exact original recording and author are not documented, so the clip is mainly known through its circulation on meme soundboards and in short form edits. Its humor comes from language mixing that French speaking and anime aware audiences both recognise instantly, which has helped it stay in use as a lighthearted reaction sound rather than a serious insult.
