How it's used
Beyond the strict chemical definition, this term is frequently used metaphorically to describe a person or event that triggers rapid change. It carries a sense of acceleration or intensification in a process that might otherwise be stagnant. When used in a figurative sense, it often implies that the outcome was inevitable but needed a push to get moving.
