What is "flema"

Flema is a Punk rock band, that managed to find a unique style in South America, among others. The last configuration of the band was: Ricky Espinosa (Vocals and Guitar), Fernando Rossi (Bass), Luis Garibaldo (Guitar), and Pepe Carvallo (Drums). Their songs usually deal with loneliness, alcohol and drugs, friends, women, politics, and complaints about the tough things in life. Their songs have titles like "Borrachos en la esquina" (drunken on the corner), "Semen de buey" (bullock semen), "el blanco cristal" (the white crystal). The band leader, Ricardo Espinosa (also known as 'Ricky') was a very controversial and beloved figure, and the core and spirit of Flema. Always drunk, always on coke, always in trouble, often the band could not play on a scheduled date because Ricky and other band members were detained at a local police station.
