A series of sharp, crackling sounds, especially the sound joints make when they pop or the sound of bubble-wrap snapping.
From Latin 'crepitatio' (a crackling), the noun form of 'crepitare.' The Latin root connects to 'crepare' meaning to crack or make noise.
Doctors use crepitation as a diagnostic clue—if your lungs sound like Rice Krispies when you breathe, it might indicate pneumonia or fluid in your lungs, and if your joints crunch loudly, it could mean cartilage wear.
