How it's used

This term is a classic example of the Cantonese suffix 嘥, which functions as a verb meaning to waste or squander. It is frequently used in household contexts to scold family members for leaving appliances running unnecessarily. The construction is highly flexible and can be applied to almost any resource, such as 嘥錢 for money or 嘥時間 for time.

Examples

Leaving the light on when not using it is such a waste of electricity.
Why are you still keeping your old computer on? It's a waste of electricity.

Common phrases

very wasteful of electricity

Common mistake

Do not confuse this with the Mandarin term 浪費, which is formal and rarely used in casual speech. Using 浪費 in a relaxed conversation with friends can sound stiff or overly serious.
