ABOUT THIS WORD

What else does flex mean?

Flex is a slang term meaning “to show off,” whether it be your physique, your belongings, or some other thing you consider superior to those of others. The act of flexing is often criticized as a power move, considered arrogant and insincere.

Where does flex come from?

The term flex has been used as Black slang for “showing courage” or “showing off” since the 1990s. Rapper Ice Cube notably used it in his 1992 song, “It Was a Good Day”: “Saw the police and they rolled right past me / No flexin’, didn’t even look in a n*gga’s direction as I ran the intersection.”

Flex comes from flexing one’s muscles, i.e., to show how physically strong you are, or, originally, how you are ready for a fight. This became a metaphor for someone displaying in some way that they think they’re better than others.

Flex came into mainstream popularity in 2014 thanks to hip-hop due’s Rae Sremmurd’s “No Flex Zone.” The song refrains: “No flex zone, No flex zone / They know better, they know better.” This no flex zone is apparently a space where you can be true to yourself, not feeling compelled to show off, judge, and put others down, i.e., hating on people and being fake.

Flex was further popularized by Rich Homie’s Quan’s 2015 song, “Flex (Ooh Ooh Ooh)” which features the lyrics: “Cause I got a check, n*ggas wanna flex / Ain’t gotta flex but I got it, ooohh.”

Flex also gained prominence in spring 2018 through its frequent use by Lil Tay, a young Canadian internet celebrity who called herself “the youngest flexer of the century.” Later that fall, the expression weird flex, but OK—a snarky response to when someone boasts about something considered odd or embarrassing—went viral.

How is flex used in real life?

Flex typically carries a negative connotation, as nobody likes a showoff or braggart. Flex can imply one isn’t being genuine (in slang, being real) or is forcing a sense of superiority (in slang, fronting).

Flex is also often used in negative constructions, e.g., a call for no flexing. It can also be a noun (instance of showing off) or a verb (to show off). Stunt is a similar slang term.
