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

Definition: This is a Cantonese slang that refers to a situation where a player has a clear opportunity to score a point. The slangs origin comes from a volleyball game where a sports announcer said "Cha SIU" instead of the word "chance". Although the word came from a volleyball game initially, it's more widely used in badminton games.

Usage: That was a total set up for a smash, total Cha SIU!

Synonym: 食叉燒
