The Underboob Pen Challenge is a trend that started in China in late January 2016. It has since then reached all corners of the Internet all around the world. The objective of the challenge is for a female to place a pen, or a similar object under her unsupported breast. It's supposed to prove weather that female is a 'real' woman or not.
Jill: Have you heard of the new "Underboob Pen Challenge?"
Sara: No, what's that?
Jill: It's yet another challenge that sets unrealistic beauty standards on women.
