To 'flex' means to bend or contract a muscle, showing off its size and strength. It can also mean to bend or curve something. Beyond the physical, 'flex' can mean to boast or show off possessions or abilities. Picture someone flexing their biceps at the gym, or a rapper flexing their wealth in a music video. The act of flexing is about displaying power and capability, whether physical or metaphorical. It's about making a statement.
