Meaning
To say or do something that makes an already difficult, tense, or angry situation even worse.
It is typically used when someone’s words or actions intensify a conflict, argument, or crisis rather than calming it down.
Origin
The image is traced back to ancient Rome and the historian Livy, who used a similar figure of speech to describe words or actions that inflamed an already heated conflict, comparing it to pouring oil onto a fire. The metaphor survived through Latin literary tradition and passed into most European languages, becoming a standard way of describing anything that intensifies a dispute rather than easing it.
Examples
Mentioning her ex only added fuel to the fire during an already tense divorce.
The politician’s careless comment added fuel to the fire just as tensions were starting to calm down.
Please do not bring up the money he owes you right now — that will just add fuel to the fire.
A: I told him his cooking was terrible, right in front of everyone.
B: Why would you add fuel to the fire like that? He was already upset.
