Perreo, a Puerto Rican dance associated with reggaeton, is a type of grinding. The word 'perreo' is derived from the Spanish word perro, meaning "dog", thus the Spanish verb for "dancing reggaeton", 'perrear', can be translated as 'dancing doggystyle'. There was also an associated Puerto Rican music genre called perreo, which served as the precursor to reggaeton. In Puerto Rico, youth perreo parties are a common part of regular nightlife. Perreo is also often called "sex with clothing" (sexo con ropa).
