Hong Kong Code-mixing Dictionary

Definition: A code-mixing term used by native Hong Kongers to refer to a friend who gets along with you very well, even though it does not always mean it is someone who you can have a deep talk with, unlike '老best' in Cantonese meaning old best friend.

Usage: E.g. 我同我“Best Friend”玩咗好多年，但實際上我從來都無同過佢講我嘅心事，心入面仲會成日妒忌佢，成日當佢係我競爭對手，究竟咁樣仲叫唔叫best friend 呢.... (E.g. I played with my "Best Friend" for years, but in fact I have never shared what is in my heart with him, and would often be jealous of him and treat him as my competitor Is that still called a best friend?)

Synonym: 最好朋友

Usage: E.g. 你哋睇下呢個係我老best。(Let me show all of you. This is my old best friend.)

Synonym: 睇下呢個係我個好朋友, 老友, old best friend
