Cách sử dụng
The expression "infra dig" is used to describe something that is beneath one's dignity or status. It is often used in formal or polite contexts, such as in business or social situations. For example, if someone were to suggest that a CEO of a company should clean the toilets, the CEO might respond by saying that such a task is "infra dig" and not befitting their position. This expression is not very common in everyday conversation, but it can be useful to know for more formal settings.
