"Pepas" is a guaracha song by Puerto Rican rapper and singer-songwriter Farruko from his studio album La 167.
He gathered a few people in the studio and asking them to sing a stadium chant that sounded similar to a church choir.
[4] "Pepas" starts off slow, then quickly picks up and morphs into something "reminiscent of pre-COVID-19 pandemic dance parties".
According to a description by Jessica Roiz of Billboard, it includes "an all-night-long rave with fireworks, dancers, men dressed in neon suits, and Farruko dancing on top of shipping containers".
Real Madrid players celebrated their comeback victories (and eventual trophy win) in the dressing rooms by singing Pepas during the 2021–22 UEFA Champions League season.
