the.com/rattling
The sound of something loose trying to warn you before it breaks entirely.
means Very good or fast, often used to describe a brisk pace, a lively story, or a general sense of excellence — as in a 'rattling good time.'
from From 'rattle,' imitating the quick clatter of loose, shaking parts knocking together — echoic in origin, likely formed simply from the sound itself. The literal sense (things clacking and shaking) gave rise to the figurative one: something moving at a rattling pace is going fast enough to clatter, and by extension anything 'rattling good' has that same brisk, lively energy.
