Merriam-Webster has added 1,400 new words and usages to its dictionary, including terms from internet culture, technology, and everyday life that have been circulating online for years. If you’ve seen “looksmaxxing” or “vibe coding” in a comment section and had no idea what they meant, there’s now an official definition to check.
Merriam-Webster confirmed the additions in an announcement published on September 15, 2026. The dictionary publisher said the additions reflect words and usages that have demonstrated widespread, sustained use over time — the standard threshold for inclusion. New entries include looksmaxxing, vibe coding, AGI (artificial general intelligence), parasocial, and cuffing season, alongside roughly 1,395 other terms spanning technology, food, emotional experience, and relationships.
Dictionary additions matter because they confirm that a word has crossed from slang or niche usage into the broader language — documented as part of mainstream English, not just internet shorthand. For readers who use these terms regularly, the update is largely confirmation. For people who’ve been confused by them, it’s a reliable place to find the actual meaning without sifting through conflicting Urban Dictionary entries.
What is looksmaxxing?
Looksmaxxing refers to the practice of taking one or more, sometimes extreme or dangerous, measures intended to increase one’s physical attractiveness — through grooming, fitness, skincare, styling, or other appearance-focused methods. The term originated in online communities and has spread widely enough that Merriam-Webster considers it established usage.
What is vibe coding?
Vibe coding refers to using an artificial intelligence system to generate computer code from a given description or prompt. The term reflects how AI-assisted programming has changed how some developers approach and describe their workflow.
Why does Merriam-Webster add new words?
The dictionary adds words when they’ve demonstrated consistent, widespread use across different types of sources over a meaningful period of time. Inclusion is documentation, not endorsement — it means the word is real and in use, not that it’s recommended or permanent.
What is cuffing season?
Cuffing season refers to the period in autumn and winter when people who are not in a relationship begin looking for a short-term romantic partner, driven in part by colder weather and the increased appeal of companionship. The term has been in wide use on social media for several years.
Karmactive has previously covered the growing influence of internet slang on formal English and how technology terms enter mainstream usage, which provides context for how terms like vibe coding move from niche to recognised.
Merriam-Webster typically announces a Word of the Year in the final quarter of the year.
