that's so fetch

'That's so fetch' is a quote from the 2004 film Mean Girls — character Gretchen Wieners tries to make 'fetch' (meaning cool) happen as a slang word, but Regina George shuts her down ('Stop trying to make fetch happen — it's not going to happen!'). The quote is now used self-consciously to celebrate something, especially in nostalgic Y2K contexts. If your teen says it, they are quoting a recognised film. Harmless and warm.

'That's so fetch' is a film-quotation catchphrase from the 2004 film Mean Girls, in which character Gretchen Wieners unsuccessfully tries to make 'fetch' (a coined slang word meaning cool or stylish) take off, prompting Regina George's iconic 'Stop trying to make fetch happen!' Now used self-consciously and humorously to celebrate something. Register: informal, pop-culture quotation. In formal writing introduce with brief gloss. A common learner mistake is to use 'fetch' alone as serious slang for cool; the joke is that it never caught on.
