Merriam-Webster welcomes ‘looksmaxxing,’ ‘vibe coding’ and ‘cuffing season’ to new word list

Merriam-Webster added 1,400 entries to its dictionary on September 20, according to Fox Business and several other outlets, representing the most extensive single‑day expansion of the publisher’s lexicon in recent memory. The new terms were incorporated across the online and print versions, giving them immediate official status. Among the additions are internet‑born words such as ‘looksmaxxing,’ a term describing the practice of enhancing one’s appearance, ‘vibe coding,’ referring to the expression of mood through digital signals, and ‘cuffing season,’ denoting the period when people seek short‑term relationships. USA Today published the full roster, while Smithsonian Magazine noted the inclusion of both niche slang like ‘Whack‑a‑Mole’ and broader cultural phrases such as ‘Sunday Scaries.’ People.com and Fox Business also highlighted the trend as evidence that internet slang is increasingly entering mainstream discourse.

The expanded lexicon directly affects educators, editors and language‑technology developers who rely on authoritative sources for curriculum design and algorithm training. Fast Company linked the surge of slang entries to rising public anxiety about AI’s role in shaping vocabulary, suggesting that the new words may soon appear in machine‑learning datasets. TribLIVE.com framed the update as a reflection of how digital communities shape language norms. Such formal acknowledgment can reinforce usage patterns and influence how platforms moderate content that incorporates these terms.

Merriam-Webster will monitor user interaction data to decide on future updates, with the publisher indicating that additional internet‑origin terms are slated for inclusion as usage stabilizes. Observers can watch subsequent releases for further evidence of digital culture’s impact on mainstream reference works. The publisher has invited public comments through its website, allowing linguists and everyday users to suggest additional entries.
