Sandungueo
Sandungueo is a style of dance and party music associated with reggaeton that emerged in the late 1980s in Puerto Rico. The dance resembles twerking. This style of dancing and music was created by DJ Blass, hence his Sandunguero Vol. 1 & 2 albums. It is a dance that focuses on grinding, also known as perreo, with one partner facing the back of the other (usually male behind female). This is also known as "booty dancing" or "grinding" in the United States of America.
