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.
