Hong Kong Code-mixing Dictionary

Definition: A code-mixing term used by westernised Hong Kongers to refer to hitting a ball towards the ground forcefully in tennis, which not only feels good when defeating someone with such a gesture, but also it sort of gives the person a feeling of breaking something into pieces.

Usage: E.g. 咁勁？！今次我要smash返你！(So powerful?! I'm going to smash you back!)

Synonym: 殺球
