"Fire in the hole" is a phrase that has come to mean 'watch out' or 'heads up'.

This phrase originated in coal mining operations as miners used dynamite to loosen rock and was a warning that an explosion was about to occur. The warning was to be shouted several times to warn other miners that the charge had been set. The phrase expanded to military usage and was utilized when grenades were thrown in confined areas as well as with bomb disposal activities.

Use Example - Rob yelled "Fire in the hole!" just before lighting the fireworks.
