How it's used
Adding 鬼 to a question word like 乜 or 邊個 intensifies the tone, signaling frustration, confusion, or impatience. It functions similarly to adding "the hell" or "the fuck" in English, though it is generally considered mild enough for casual use among friends. When used as a standalone exclamation, it expresses strong disbelief or annoyance at a situation.
Examples
What the hell are you doing?

Common mistake
Avoid using this in formal settings, professional environments, or with people you do not know well, as it can sound aggressive or rude. It is strictly for informal, emotional, or colloquial speech.
