The Chinese word **裂开 (lièkāi)** is a verb-object compound formed by combining the character **裂 (liè)**, meaning "to split" or "to crack," with **开 (kāi)**, meaning "to open" or "apart." Literally, it describes the action of an object cracking open or splitting apart (e.g., "the ground裂开"). In modern internet slang, its meaning has expanded metaphorically to express a state of mental or emotional breakdown, overwhelming shock, or being utterly unable to cope with a situation, effectively capturing the vivid image of one's composure or mind "splitting open" under pressure.
