How it's used
Functions as a formal idiom that describes a situation where an action produces the exact opposite of the intended outcome. While it is a four-character idiom, it is frequently used in spoken Cantonese to provide a concise and punchy conclusion to a story about a failed plan. It carries a slightly intellectual or analytical tone compared to more casual phrases like 搞砸咗.
Examples
Forcing him to study like this will only backfire.
I wanted to help but it backfired, how awkward.
