'OK,' but often passive-aggressive in tone.

Texting universal.

Why teens actually say it

Compact agreement OR flat dismissal — tone decides.

What it means for you as a parent

Sometimes a sign of friction with a friend or partner — worth a gentle check-in.

How it’s used

  • “Fine, do whatever.” “k.” Clipped reply that signals annoyance more than agreement.
  • “So we’re still on for 6?” “k” Could be neutral or cold — tone leaves the other person guessing.
