A snowball effect
Meaning
A situation where an initial small action or event leads to a series of increasingly larger or more significant consequences.
Origin
Imagine a small, seemingly insignificant snowball, no bigger than your palm, pushed gently down a pristine, snow-covered slope. As it tumbles, it picks up more snow, gradually expanding its mass and momentum. With each rotation, it grows larger, faster, and more powerful, until it's an unstoppable, massive orb, far beyond its initial humble size. This vivid, physical phenomenon, observed for centuries by anyone living in snowy regions, perfectly encapsulates the concept of a chain reaction where a minor initial event gains unstoppable momentum, leading to ever-greater consequences, and thus became a powerful metaphor for exponential growth or escalation.
Examples
