View original article & transcriptWhen a machine or process “goes haywire,” it stops working as expected or becomes disorganized. A plan can also “go haywire” when several things go wrong. In informal speech, a person may say they are “going haywire” when they feel overwhelmed, but that wording can sound stigmatizing; describe the feeling or situation more specifically. The source itself presents more than one possible explanation for the idiom’s history.
Cultural note: “Go haywire” is informal and vivid. Avoid using “crazy,” “berserk,” or “run amok” as casual labels for people experiencing distress; they can stigmatize or exaggerate. A machine malfunction and a person’s mental health are not equivalent. The proposed origins involving temporary farm repairs or wire springing loose are possibilities, not settled etymology.
Keep exploringA device, schedule, or carefully planned event can go haywire—but describing a person deserves more care.
