What phrase describes the tendency to take chances for the sake of showing off?

The phrase that describes the tendency to take chances for the sake of showing off is "machismo." This term embodies a strong or exaggerated sense of masculinity and may involve taking risks or acting in a way that seeks to demonstrate strength or bravery, often in a socially or culturally significant manner. Individuals exhibiting machismo may engage in risky behaviors not purely for the sake of necessity or challenge, but rather to display their prowess or assert dominance in a social context.

Bravery implies courage and is often associated with noble acts that may involve risks, but not necessarily for the sake of appearances. Self-assuredness indicates confidence in one's abilities but does not imply taking risks for show. Overconfidence suggests an excessive belief in one’s own capabilities, which might lead to risky behavior, yet it lacks the social aspect emphasized by machismo. Understanding these nuances helps clarify why "machismo" is the most fitting term in this context.
