Running the fire out of the slippers: “Make an extreme effort”
Be on fire: “Be very enthusiastic”
Throwing oil on the fire: “Escalating a controversy further”
Where there’s smoke, there’s fire: “Every event has a cause”
Daring to put your hand in the fire for something: “To be convinced of something without reservations”
Playing with fire: “Undertaking something that will probably end badly”
