IPA: /ˈbloʊˌbæk/
KK: /ˈbloʊˌbæk/
An unexpected and often negative consequence or result of an action, especially in politics or other decision-making processes.
The new policy had significant blowback, leading to protests and public outcry.
Blowback is formed from "blow" (from Old English "blāwan", meaning to emit air) and "back" (meaning in the reverse direction). The term describes the unintended consequences or backlash that occur as a result of an action, often referring to the repercussions that come back to the source.
Think of 'blowing' air and having it come 'back' at you — that's how blowback refers to the consequences returning to the origin.
