twerk

A dance movement characterized by a rhythmic gyrating of the lower body in a sexual manner with the intent to elicit arousal or laughter in one's dance partner and/or audience, it mainly involves thrusting hip movements and a low, squatting stance.

Historical perspective: Miley Cyrus' performance at the 2013 VMA’s generated an online buzz about twerking. Its 15 minutes of YouTube fame was over by the end of this year after everyone and their mother went as a twerking Miley for Halloween.
