TWICE’s Sana wiggles her butt as fellow member Dahyun slaps it … for science!

TWICE members Sana and Dahyun got intimate with each other at a recent fanmeeting, with Dahyun hitting Sana’s ass, which then triggered Sana into shaking said ass while Dahyun slapped it around.

This is not sexualizing these two upstanding young women, but rather it’s an article about the curious dynamics of non-verbal interpersonal communication between female idol group members and how it connects to front stage/back stage personas … if you really think about it.

Science, bitches.
