in and out

Briefly present then absent

In and out describes movement or action that alternates between entering and exiting, or presence that's intermittent: She's been in and out of the hospital all year.

It can mean quickly completed: It was an in-and-out procedure—I was home by noon.

The phrase also describes thorough knowledge: He knows the system in and out.

In-N-Out is an American fast-food chain.
