Also known as: 手放しタピオカ, タピオカチャレンジ, タピ岡チャレンジ, バブルティーチャレンジ, 珍珠奶茶挑战
A Meme in which a character balances Bubble Tea (or a similar Drink) on their breasts while drinking it.
The Meme originated on Twitter in June 2019 when Japanese model @hcupadman posted a video of herself drinking a latte balanced on her chest [1]. Later Himura Kiseki, the creator of the Tawawa Challenge, posted a comic of Ai-chan performing the same act with Bubble Tea (post #3532540).
A common gag is for flat-chested characters to cheat or fail at the challenge. If boys participate in the challenge at all, they will often be balancing the object on prominent Manboobs or Large Pectorals.
