locked in.
Fully focused and committed to a task. “Time to lock in” means it is time to stop distractions and concentrate.
What does locked in mean?
Someone who is locked in is concentrating closely and taking the task seriously. In sport or gaming it can describe sustained attention; in a study chat it announces a switch from distraction to work. It is about focus, not a guarantee of success.
“Lock in” can be an instruction to yourself or someone else. The same phrase has ordinary meanings: to secure a rate, commit a choice, or physically lock something inside. A message saying “the booking is locked in” usually means confirmed, not mentally focused. Look at what follows the phrase and what kind of activity is being discussed.
