the.com/repercussion

The echo you ignored when you did the thing anyway.

means A consequence that follows from an action, often one that strikes back harder than expected.

from From Latin repercussio, 'a rebounding or echoing back,' built from re- ('back') plus percutere ('to strike through, beat') — the same root that gives us 'percussion.' The word originally described literal echoes and the reflection of light or sound bouncing off a surface, before it settled into its modern sense of consequences that bounce back at you, sometimes louder than the original act.
