Lock in means to fully focus and commit. When your kid says "I need to lock in" before exams, they mean they are going to stop scrolling and concentrate. It comes from gaming and sports culture. This is one of the more positive Gen Z phrases. It is not drug-related and not concerning. Encourage it. You might also hear "locked in" meaning fully focused, or "we need to lock in" before a group project.

Enter intense-focus mode. Same as "locking in" but as imperative or noun — "we need to lock in," "it's lock-in time." Usually announced at 11pm the night before a deadline; the announcement consumes the next 30 minutes of productive time.

For parents
Lock in means to fully focus and commit. When your kid says "I need to lock in" before exams, they mean they are going to stop scrolling and concentrate. It comes from gaming and sports culture. This is one of the more positive Gen Z phrases. It is not drug-related and not concerning. Encourage it. You might also hear "locked in" meaning fully focused, or "we need to lock in" before a group project.
For ESL learners
Lock in is informal but increasingly mainstream. The formal equivalents are "focus," "concentrate," or "commit to a task." Safe in casual speech with peers, gym partners, and gaming friends, but avoid it in business writing where "focus" or "commit" sounds more professional. A common mistake is using "lock in" to mean "agree on a decision" the way a native might say "lock in a deal"; those two senses are different, and context matters.

For specific readers
Why is this section here?
Slang is read by different audiences for very different reasons. The For parents view re-explains the term in plain, non-judgemental language so a caregiver can understand what their child means without needing the surrounding subculture. The For English learners view focuses on register (when it's safe to use), formal alternatives, and common mistakes — what a textbook won't teach you.
