Okay kiddo, "Yo perreo sola" is a Spanish phrase that means "I dance alone". It's a song by a really cool artist named Bad Bunny.
Dancing is when you move your body to the beat of music. In this song, Bad Bunny is saying that sometimes she wants to dance all by herself, without anyone else around. It might seem strange to dance alone, but sometimes it's really fun to just move your body and be free!
The words "perreo" and "sola" both come from Spanish. "Perreo" refers to a type of dance where you move your hips a lot, and "sola" means "alone". So together, "yo perreo sola" means "I dance all by myself, doing my own thing and having fun!"
Basically, Bad Bunny is saying that she doesn't need anyone else to enjoy dancing - she can do it all on her own! And that's a pretty cool thing to be able to do.
