The term “infra dig” is a colloquial expression that comes from the Latin phrase “infra dignitatem,” which means “beneath one’s dignity” or “beneath contempt.” When someone uses this term, it usually means that they consider something to be beneath them or not worthy of their respect or consideration. It implies that the person has a negative opinion or judgment about something and views it as unworthy of serious attention or concern.
For example, if someone were to say, “I won’t stoop to his level; it’s all just infra dig,” they would mean that they believe the situation or person in question is so insignificant or worthless that they won’t bother giving them any importance.
