Global English Word Watch #5: sigma, gyatt, lock in and cooked

The Urban Dictionary date for each term below is the oldest dated entry I found on the checked page or matching variant during this week's research. Urban Dictionary is user-submitted: an early entry records visible usage by one contributor, not the word's proven coinage. Where the oldest entry uses a different sense, that distinction is stated.

These four terms show different routes into wider English: a manosphere label turned Gen Alpha meme, African American English pronunciation amplified by livestreaming, focus language recast as a TikTok challenge, and an old informal expression repackaged by online communities.

Meaning. In current internet slang, sigma can describe a coolly independent and successful man. It can also mean "extremely good," or function as an intentionally meaningless meme phrase such as "what the sigma." Merriam-Webster notes that the word is especially associated with young men and may be used ironically or critically. 1

Urban Dictionary. The oldest dated record I found for the matching sigma male grindset usage is 13 August 2021. That entry frames the "sigma" as a supposedly superior male in a social hierarchy; it is a user-submitted record, not proof that the term began on that date. 2

Background. The modern sense grew out of manosphere vocabulary, where "sigma male" names a lone-wolf archetype alongside hierarchy terms such as alpha and beta. UN Women includes it in a glossary of manosphere language, while Merriam-Webster describes its later spread among young men and its newer use as nonsense or meme speech. That route matters when the word appears to be a harmless compliment: in some contexts it still carries the status-ranking and masculinity politics of its source communities. 13

Meaning. Gyatt or gyat is an exclamation of excitement or admiration, especially about a person's large or shapely buttocks. It is also used as a noun for the body part or, in some uses, the person being described. Merriam-Webster and Cambridge both note the term's sexualised focus; Cambridge also records its use among younger speakers. 45

Urban Dictionary. The oldest dated entry I found for the matching Gyatt Damn page is 22 September 2023. It describes the phrase as internet slang for praising a curvy woman's body. That is a user-submitted usage record, not a neutral definition or proof of coinage. 6

Background. Merriam-Webster traces gyatt to goddamn, with spelling and pronunciation patterns associated with African American English. It says the term was visible online by the late 2000s, then spread more widely in the early 2020s through social media and livestream gaming; the streamer YourRAGE helped popularise the exclamation in 2021 and narrow its common sense toward comments about women's bodies. Because that usage can objectify people, the word may read as offensive rather than playful. 4

Meaning. To lock in is to enter a state of deep focus and sustained commitment to a task or goal. Merriam-Webster gives examples tied to work, money and sport, and notes that the phrase has circulated online since at least the 2000s. 7

Urban Dictionary. The oldest dated entry I found on the checked lock the fuck in page is 6 August 2023. A later entry dated 7 February 2024 states the focus sense directly, describing someone as "120% focused on a task." Both are user-submitted records; the earlier date belongs to a matching variant, not a proven first use of the shorter phrase lock in. 8

Background. Sports and video-game streamers helped the focus sense circulate online, but its biggest recent jump into general lifestyle language came through the TikTok trend called the Great Lock In. The New York Times reported in September 2025 that participants used the challenge to pursue goals from September through the end of the year, rather than waiting for New Year's resolutions. The phrase can therefore signal either a quick instruction to concentrate or a whole self-improvement routine, depending on the post around it. 79

Meaning. In current online use, cooked means doomed, finished, or in a state of likely failure: "Are we cooked?" asks whether a situation is effectively over. Merriam-Webster describes the slang sense as a state of possibly irreversible misfortune and connects it to the older informal meaning of being "done for." 10

Urban Dictionary. The oldest dated entry I found on the exact cooked page is 17 September 2004, but that entry uses cooked to mean tired after drinking or partying. The oldest entry on that page matching the broad modern negative evaluation is 2 December 2016. A matching you're cooked entry dated 21 February 2024 explicitly uses the word for being screwed or doomed and says the usage was popularised by Twitch streamer Tbvnks. All of these are user-submitted records, and none proves a single point of coinage. 1112

Background. The modern form is less a new invention than a change in setting and rhythm. Merriam-Webster traces the "done for" sense back to the nineteenth century, while examples from recent online speech show it being used as a short, dramatic verdict in gaming, work and everyday mishaps. The expression is usually informal; the surrounding words tell you whether it is a real prediction of failure, self-mockery, or a joke about internet panic. 10

The dates do not line up with the moments these terms became visible to a broad audience. Sigma moved from manosphere status language into ironic Gen Alpha meme speech. Gyatt carried a pronunciation associated with African American English into livestream and social-media commentary. Lock in turned a focus instruction into a named TikTok challenge. Cooked shows the reverse pattern: an older informal sense gained a sharper online formula and new circulation through streaming culture.

Context still determines the temperature. Sigma can be praise or parody; gyatt can be a meme or an unwelcome comment about someone's body; lock in can be practical advice or lifestyle branding; and cooked can be a serious assessment or a deliberately exaggerated punchline.
