Flex

To flex means to show off or display something, usually in a boastful manner. This can be related to physical strength, wealth, style, or any other personal achievement. It’s often used in a context where someone is trying to impress or brag.

“He was flexing his new car all over social media. I guess he’s really proud of it.”
