Polilla literally translates to "moth". In this party anthem, it's used in the fun Caribbean idiom "botar la polilla", which literally means "to throw out the moth".
This colorful expression means to go out and dance your heart out, as if you're shaking the dust and moths off old clothes that have been in storage. It's a memorable way to say you're letting loose on the dance floor and getting rid of old, stagnant energy.
This is a classic reggaeton track about pure physical chemistry. Daddy Yankee, along with Wisin & Yandel, remembers the very beginning of a relationship, kicking off with the line, "Esta noche está buena pa hacer maldades" (Tonight is a good night to be mischievous). Things moved fast, and now both sides are completely hooked on each other, begging the other not to leave them alone.
The chorus is a back-and-forth between the man and the woman: "Mami, no me dejes solo" (Baby girl, don't leave me alone) and "Papi, no me dejes sola" (Daddy, don't leave me alone). The song is filled with playful, over-the-top metaphors for sex and attraction. Daddy Yankee compares himself to the "caldo pa esa caserola" (broth for that pot) and the "abono que está pidiendo esa amapola" (fertilizer that poppy is asking for). It's a high-energy dance track all about intense desire.
