What does LOCA stand for? 

Loca

Loca (English: "Crazy") is a song by Colombian singer-songwriter Shakira, taken from her seventh studio album, Sale el Sol (2010). It was released by Epic Records as the lead single from the album. The Spanish-language version features Dominican rapper El Cata, and was released on 10 September 2010, while the English-language version features British rapper Dizzee Rascal, and was released on 13 September 2010. It was written and produced by Shakira, with additional songwriting from Edward Bello, Armando Pérez, and Dylan Mills. The song is a Latin pop and merengue track that lyrically describes Shakira's eccentric infatuation with a man. In August 2014, a senior US district judge found "Loca" to have been indirectly plagiarised from "Loca con su Tiguere", a mid-1990s song composed by Dominican songwriter Ramon "Arias" Vasquez. The case was dismissed in August 2015 after it was found that Vasquez had fabricated the evidence he had presented in court. Upon its release, "Loca" received generally favourable reviews from music critics, who complimented the inclusion of merengue music on the recording. The English version of the song became a worldwide commercial success and peaked inside the top five of the record charts of countries including Austria, Belgium, France, Hungary and Italy. The Spanish version peaked atop the charts of Spain and Switzerland, and became a hit on the Latin record charts in the United States, topping the Billboard Hot Latin Songs, Latin Pop Airplay, and Tropical Songs charts. "Loca" received record certifications in various countries around the world, including a diamond certification in Colombia and multi-platinum certifications in Italy, Mexico, and Spain. The song has sold over 5 million copies worldwide, and is noted to be the best selling merengue song of all time. Its accompanying music video was filmed in Barcelona, Spain in August 2010, and was released the following month. It features Shakira interacting with a beach crowd, and dancing in front of the sea wearing a golden bikini. It generated a favourable response from critics, many of whom praised its concept for matching the vibe of the song. For additional promotion, Shakira performed "Loca" on several television shows and on her The Sun Comes Out World Tour.
