- 1瘋了、神經（口語；不是醫生用語）
Loco is an informal, slightly playful way to say crazy — not a careful medical word, and not polite in a serious conversation about someone’s mind. English borrowed the adjective from Spanish loco, “insane” or “crazy.” You will hear it in American English more than in careful British English: go loco, a loco idea. It can be teasing among friends, or a bit rude if you aim it at a person who did not ask for the joke. Though actually, English also has loco as a short form of locomotive, the train engine; that is a different word in real life, even if it looks the same on the page. For this sense, think “wild in the head,” not “train.”
From the word’s history
