Rebolation, from the Portuguese verb rebolar - "to sway" or "to swing",[1] is a style of Brazilian dance that originated in rave parties in the early 2000s. The dance, which gained popularity in 2007 after videos of people practicing the dance were uploaded to popular Internet video sharing websites, such as YouTube, is mainly performed to electronic music, often psy trance or electro house, and involves moving the arms and legs loosely while coordinated footwork makes the dancer appear to slightly hover above the floor.[2]
