What does “on fire” mean in everyday English?

When you say something is “on fire,” you mean it is doing really well or is very impressive. It has nothing to do with actual flames. You can use it for food, a person, a team, or a performance: “That meal was on fire,” “She’s on fire today,” “This band is on fire.” It is a very common phrase in casual English, especially when you want to sound excited.

In this clip, the speaker opens with “This dinner was on fire” — meaning the meal was excellent. What makes the moment special is the double meaning: the restaurant actually uses a flame torch to cook the beef brisket and eggs right at the table. So the food is literally on fire, and the dinner is also on fire in the phrase sense. This double meaning is a good way to remember the phrase. You can use “on fire” any time something impresses you: “Your English is on fire!” or “That coffee shop is on fire right now — everyone is talking about it.”
