Etymology
As an analogy to a state in a multispeed internal combustion engine in which improperly synchronized inputs and outputs in the transmission during a gear shift (as by driver error or a mechanical fault) lead to literal grinding of gears against each other as they're forced to mesh at different speeds from one another. The noise produced is harsh and grating, and damage to the transmission can accumulate with repeated occurrences.
