Sandungueo, also known as perreo, is a style of dance and party music associated with reggaeton that emerged in the late 1980s in Puerto Rico. This style of dancing and music was created by DJ Blass, hence his Sandunguero Vol. 1 & 2 albums and popularized and spread worldwide by the website Sandungueo.com.[1]
It is a dance that focuses on moving the hips. It can be danced in many ways. Men and women dance it differently. Perreo, like most dances can be danced alone by moving the hips or it can also be danced with a partner. Bad Bunny made a song called "Yo Perreo Sola," a song for women to emphasize that perreo can also be danced alone and not necessarily with a partner. This goes back to Ivy Queen, who empowered the reggaeton culture by putting in her songs a message for women that they're the ones that can take the lead and remind them that respect is important in perreo.
