Meaning
To engage in a dangerous, risky activity, or to provoke a volatile situation, often while underestimating the possible consequences.
It’s frequently used as a warning, spoken to or about someone taking an unnecessary and avoidable risk.
Origin
The phrase is rooted in the literal, immediate danger of handling open flame carelessly — a child playing with matches or an unattended fire is a universally recognized image of a small action that can escalate quickly into serious, irreversible harm. This makes it one of the more transparent idioms, requiring no historical incident or literary coinage to explain it: the metaphor works because the literal action it describes is dangerous in exactly the way the figurative situation is. Versions of the same fire-based warning appear independently across many languages and cultures, since the physical danger of fire has been a universal human experience since prehistory, long before any language had developed the specific figurative idiom built on it.
