What does flex mean?

Flex comes from flexing your muscles to show how strong you are. In slang, the “muscles” can be anything: designer clothes, a big paycheck, a vacation, good grades or famous friends. Flexing can be harmless pride or obnoxious bragging, depending on how it’s done.

A “humble flex” or “humblebrag” disguises showing off as modesty: “Ugh, I hate how my Harvard hoodie shrank in the wash.”

How to use flex

  • “He’s always flexing his sneaker collection.”
  • “Not to flex, but I finished my essay a week early.”
  • “Paying off your student loans at 25 is a real flex.”
  • “Weird flex but OK.”

“Weird flex but OK”

This reply mocks a strange or pointless thing to brag about: “I’ve never read a book in my life.” “Weird flex but OK.” Merriam-Webster traces it to a December 2017 reply on Twitter, and Know Your Meme notes it went viral in September 2018.

Where flex comes from

The slang builds on the idea of flexing muscles. Merriam-Webster points to Rae Sremmurd’s 2014 hit “No Flex Zone” as a big boost for the word’s popularity.
