An emergency of the salsa variety. Usually used in the process of preparing salsa con queso while trying to find the perfect balance of salsa and cheese. Whenever there is too little or too much salsa, there's a salsa emergency. To emphasize the urgency of the situation, "Salsa Emergency!" should be shouted whenever a salsa emergency is discovered.
I know you're concerned since we're usually the ones in charge of salsa emergencies.
I was preparing the salsa con queso for Cinco de Nacho and we had a salsa emergency.
