the word flex usually means to bend a joint, but in this case, to flex something means to steal something that is not yours, so its a verb.

Flex Day

December 26th is flex day. Show off all of your expensive items to your friends. You can also flex with the new items you got at Christmas.

"Billy it's December 26th which means it's flex day, I bet you don't have the iPhone 11 Pro Max."
Billy answered while holding back tears, "you're right Joe, I don't."
Billy replied, "wait, who's Joe?"
