spring up
Pop into existence
To spring up is to appear or emerge suddenly, often in abundance: New coffee shops are springing up all over the neighborhood.
The phrase suggests rapid, almost effortless growth—like plants sprouting from soil.
It applies to businesses, buildings, movements, or problems that seem to materialize quickly: Rumors sprang up overnight.
