Originates from sumo wrestling, where it describes a bout fought with genuine effort rather than being fixed (八百長(やおちょう)). The name is said to come from the sound of wrestlers' heads clashing (ガチンと). In modern slang, it has expanded far beyond sumo to mean anything done seriously and for real. Often shortened to ガチ in casual speech.
