Piquete is a popular slang term in Caribbean Spanish, especially in the world of reggaetón and dembow. While it can literally mean a 'sting' or 'prick', in this context, it means 'swag', 'style', or a unique, confident flair.
In the song, El Alfa boasts, "Demasiado piquete manín, se me fue los frenos" (Too much swag, man, my brakes gave out). He's saying his style and energy are so powerful and out of control that he can't be stopped. It's a key word for understanding the confident and boastful attitude common in the genre.
This song is built around a hilarious and very direct idea. The singer says he was going to film a woman in low quality, but she told him no way: "Ella lo que quiere es que la ponga en 4K" (What she wants is for me to put her in 4K). In this track, "4K" is a metaphor for the best of everything. It's not about TVs; it's about a high-definition lifestyle of luxury, money, and intense experiences.
The artists spend the whole song bragging about how they can provide this 4K life. They boast about their wealth with lines like "Estoy cobrando por party más de 70k" (I'm charging over 70k per party) and promise to buy her anything she wants. The song is a classic dembow party anthem, full of energy and confidence, all about living life at the highest possible resolution.
