Cách sử dụng
The expression "catch/touch somebody on the raw" means to say or do something that greatly upsets or offends someone. It usually refers to a sensitive or personal issue that someone does not like to talk about. For example, if you make a joke about someone's weight, it might touch them on the raw because they are sensitive about their appearance. This expression should be used in informal situations with people you know well, as it can be quite strong and hurtful.
