Chocas comes from the verb chocar, which literally means "to crash" or "to bump into," like in a car accident. It's a common verb, but the song gives it a very specific, high-energy meaning.
In the context of reggaeton and this track, chocar describes the act of two people bumping or grinding their bodies together while dancing. It captures the physical, rhythmic, and provocative nature of the dance style that the song is all about, making it the central action of the lyrics.
Plan B doesn't waste any time getting to the point in this song. The very first lines tell you everything you need to know: "No sé por qué / Pero cuando te veo lo único que pienso, mami en sexo" (I don't know why / But when I see you the only thing I think about, mami, is sex). The whole track is about an overwhelming physical attraction to someone. The key word here is "choca," which means to crash or bump. In the song, it's all about the way two people's bodies connect while dancing, creating a ton of heat and chemistry.
The lyrics are a long list of compliments about this woman, admiring everything about her. The singer says she's beautiful in every possible way: "Tú eres bonita con ropa, tú eres bonita sin nada" (You're beautiful with clothes, you're beautiful with nothing). It's a song that celebrates pure, unfiltered desire and the intense connection you can feel with someone on the dance floor.
