bounce off the walls

Wildly restless behavior

To bounce off the walls is to be hyperactive, restless, or unable to contain one's energy—like someone so energized they're careening around a room: The kids were bouncing off the walls after all that sugar.

The phrase often describes children or anyone in a state of excited agitation.
