restless
毷 centers on a state of restless agitation, like a mind or body that cannot settle down.
毷 combines 毛 (hair) with 冒, which likely contributes the sound and may suggest a covering or rashness. The exact historical development is uncertain.
Imagine hair (毛) standing on end under a rash impulse (冒), making the whole body feel restless and unable to stay still.
For ボウ, picture a restless person pacing back and forth with a bow (ボウ) in their hair, unable to settle down.
