heart-shaped boob challenge
The heart-shaped boob challenge (Chinese: 桃心胸挑战) is a trend in which women post selfies of themselves making a heart-shape over their breasts such that their hand covers their nipple. The trend, which began in July of 2017 on Chinese social media, was seemingly started by a Chinese live-streamer by the name of Ayi Xi Tai Lǜ (@阿姨洗太绿).
