To shut out distraction and give something your full, committed focus.
“Finals next week — time to lock in.”
Origin & Attribution
Lock in was ordinary Black speech well before it became a meme. The oldest datable definition of the focus sense appears in 2009, years before TikTok existed, and the phrase was circulating on Black Twitter by 2011 — students bracing for exams, players getting right before a game, anybody shutting the door on everything but the one thing in front of them. When it reached national attention around 2023, the press credited gaming streamers and Gen Z, and Merriam-Webster's entry still routes the history through sports and esports without naming the speakers who carried it. The American Dialect Society voted it Most Useful Word of 2024. The 2020s did not invent lock in; they overheard it.
