Meet Polyester: Gen Zs new way to call you fake

Nobody online wants to be polyester right now.

That is not a compliment.

According to the Gen-Z lexicon, something "polyester" is a way of saying it feels cheap, mass-produced, low-effort, or inauthentic.

It might look polished at first glance, but underneath the sheen, something about it feels artificial.

A generic influencer brand can be polyester.

An overly polished video can be polyester.

So can your relationship.

The insult draws on the fabric’s increasingly poor online reputation.

Polyester is a synthetic fiber made from plastic, and younger shoppers have spent years complaining about finding it in expensive clothing , purging it from their closets , and searching for cotton, wool, and other natural materials instead.

Polyester is not necessarily low-quality — different versions of the material have legitimate uses, including in performance clothing — but online fashion discourse often treats the word as shorthand for the cheap, shiny fabric associated with fast fashion.

That made it particularly effective as an insult for anything that looks manufactured or disposable.

Where did the polyester meme come from? Before people had polyester lifestyles, TikTok had "polyester edits." The term emerged around a style of aggressively edited fan video featuring characters such as Spider-Man and Iron Man.

The videos layer poses over rapidly flashing footage, usually accompanied by metallic music and enough visual effects to make CapCut beg for mercy.

According to Know Your Meme , examples of the editing style appeared as early as October 2025.
