Making a series of sharp, crackling sounds like popcorn popping or dry leaves crunching underfoot.
From Latin 'crepitare' (to crackle), derived from 'crepare' (to crack or burst). The present participle form adds '-ing' to describe an ongoing crackling action.
Your knuckles crackle when you crack them, your joints crackle when you stretch—these crepitating sounds are actually tiny bubbles of gas collapsing in your body's fluid-filled spaces, which is why doctors listen for them to diagnose joint and lung problems.
