✔ On the ball

INFORMAL

============

■ Meaning:

If you’re on the ball, you’re alert and you know what’s going on around you.

■ For example:

  • I didn’t get much sleep last night so I’m not really on the ball today.
  • My brother is always on the ball, so it’s hard to trick him or catch him unawares
