문화적 배경

In the world of bullfighting, 'sangre fría' is one of the most respected traits a matador can have. It represents the ability to stand still while a half-ton animal charges at you. In Mexican business culture, being 'de sangre fría' is often associated with 'colmillo' (experience/shrewdness). It means you can't be easily intimidated in a negotiation. In Argentina, the phrase is often used in football (soccer) to describe players who are 'pecho frío' (cold-chested/lacking passion) vs 'sangre fría' (composed). 'Sangre fría' is the positive version. In Colombian urban slang, 'sangre fría' can sometimes refer to someone who is 'frentero' (direct) and doesn't fear consequences, though the standard meaning remains dominant.
