How it's used

Adding 鬼 to a question acts as an intensifier that conveys frustration, confusion, or annoyance. It is significantly more informal than simply asking 搞乜, which is a neutral way to ask what someone is doing. Use this phrase when you are genuinely baffled by a situation or someone's behavior.

Examples

What on earth are you doing there?
What is going on with the power cuts all the time?

Common mistake

Avoid using this in formal settings or with people you do not know well, as the inclusion of 鬼 can sound aggressive or rude depending on your tone of voice.
