Hong Kong Code-mixing Dictionary

Definition: A code-mixing phrase used by native Hong Kongers when they are really considerate about offending someone before or after saying something, such as making a comment or remark. However, it can be entirely offensive sometimes even though the person says no offense.

Usage: E.g. 成日開口埋口都講No Offense嘅人，其實先係最Offense。(The person who always says no offense is very often the person who is the most offensive.)

Synonym: 有怪莫怪, 無意冒犯
