Finding courage with 気が大きくなる
The expression 気が大きくなる describes a psychological state where someone becomes overly confident, bold, or carefree, often to the point of being reckless or indulgent. This phrase is typically used in situations where a person’s emotions or circumstances cause them to behave in a way that they might not normally. It is often a temporary change in state of mind, such as being emboldened due to external factors (e.g., alcohol, winning a game, or peer influence).
