The bizarre trend started when a well-known Japanese artist shared a sketch of a character using her chest as a bubble tea cup holder.
It sparked a hashtag (that translates roughly to) #handsfreebubbletea that quickly went viral, Asia One reports and caused women across the country to share photos of themselves making the most of their womanly assets for ease of drinking.
The bizarre boob trend quickly caught on, with women around the world getting in on the selfie action.
Even men — who are missing a critical element required, boobs — have tried to get in on the action, with hilarious results.
WHAT IS BUBBLE TEA?
While it has plenty of different names across the world, such as pearl milk tea and tapioca tea, it's most commonly known as bubble tea.
According to MIC, the term "bubble tea" is actually a reference to the milk froth that forms when the drink is shaken, not the chewy pearls in the drink that resemble bubbles, Quartz noted. It states the term "boba", on the other hand, originates from a Taiwanese slang term for pearls.
The balls can be made of a variety of ingredients, including jelly, tapioca, custard, milk and even coffee.
HIDDEN DANGERS OF THE PEARLS
While the drink has boomed recently, it's not been without controversy — a teen girl had to be rushed to the hospital because of her addiction to the tea drink.
Her obsession led to her hospitalisation, and doctors were stunned to find more than 100 bubble tea pearls accumulated inside her and stuck to her digestive tract.
A report by Chinese media outlet Shaoxing News claimed the 14-year-old, Xiao Shen, had complained to her parents of extreme stomach pains, with an X-ray revealing the balls lodged inside her stomach.
