ETYMOLOGY
The term went viral during China's 2017 social media frenzy when a pop star's "20-year friendship" with another celebrity was exposed as fake. Netizens compared their bond to "plastic flowers from Yiwu Market – forever blooming but reeking of artificiality."
It reached peak popularity during 2018's idol survival show Produce 101 China. Contestant Wang Ju famously said: "Some sisterhoods are like cling wrap – tightly sealed before cameras, instantly torn backstage." Her "cling wrap analogy" sparked 480K+ meme creations within 24 hours.
Modern usage example:
Faux Sister 1: "OMG babe, those jeans make you look SO slim!" (inner monologue: She looks like a stuffed sausage)Faux Sister 2: "Love youuu! That lipstick is EVERYTHING!" (secretly Googling: how to remove neon pink stains from silk blouse)
