Cartel de Santa and Millonario turn a night out in Monterrey into pure party bragging. The hook says it all: "A ellas les gusta volar y volar y volar, mientras las pongo a bailar" (they like to fly and fly and fly, while I get them dancing). "Volar" here means getting high, and each round of the chorus swaps in what fuels the night: a whisky, a "trippy", a "moly" (slang for MDMA), or the money he throws at them.
The verses are fast Mexican street slang. "Clavada en la troca" (stashed in the truck) is where he keeps his gun, a troca being a pickup truck, and chamacas are girls. "La feria me llueve automática" (the money rains on me automatically) uses feria, Mexican slang for cash, and lana (wool) means money too, as in "quieren mi lana" (they want my money). A regiomontana is a woman from Monterrey, the band's home city.
Be warned: a lot of this is very explicit, with lines about sex and plenty of swearing, so treat it as a slang lesson rather than something to quote at dinner. The bragging is so over the top, from yachts and planes to "el avión no aterriza" (the plane never lands), that it is half funny.
