Spread like wildfire
English Idiom
Meaning: When something becomes popular or known very quickly, similar to how a fire spreads rapidly in a forest, it can be said to spread like wildfire.
Origin: The idiom 'spread like wildfire' originated in the early 19th century, drawing a comparison to the rapid and uncontrollable spread of wildfires, especially in dry, wooded areas. Wildfires can engulf large areas in a short period, making the phrase a powerful metaphor for something that disseminates quickly.
