Someone who chokes under pressure, especially in sports. Literally "cold chest," it describes a player or person who lacks passion and disappears in clutch moments. In Argentine and Uruguayan football culture, calling someone a pecho frío is one of the harshest criticisms, it means they have no heart when it counts. It can also be used outside sports for anyone who does not step up when the stakes are high.

To show your true colors, to reveal who you really are underneath the facade. Literally "to show the loose threads," like cheap clothing that falls apart and exposes what is underneath. It is used when someone drops their mask and their real intentions, flaws, or character come through. Common across Latin America, especially when someone who seemed trustworthy turns out to be shady or selfish.
