Sandungueando is a fantastic slang word you'll only hear in the world of reggaeton and Caribbean music. It comes from the word sandunga, a noun that means grace, charm, or a party-loving spirit.
When Zion sings "Sandungueando todos pa'l suelo" (Everyone sandungueando to the floor), he's describing a specific way of dancing with a flirtatious, rhythmic, and groovy vibe. It's a word that perfectly captures the fun and energy of the song.
This is a classic reggaeton party starter all about intense, mutual attraction. The singer is completely captivated by a woman on the dance floor. He repeats over and over, "Ella hace todo por seducirme / Y yo voy, voy, voy" (She does everything to seduce me / And I go, go, go). He's not complaining, though! He's thrilled to follow her lead, singing that he's "Haciendo lo que ella me pide" (Doing what she asks of me) because "fue la que siempre quise" (she was the one I always wanted).
He gets very protective, warning everyone else at the club, "Que nadie me la vele / O haré que todos vuelen" (Nobody better watch her / Or I'll make them all fly). The whole song is set in a club that's about to "estallar" (explode) with energy. The goal for the night is to dance "Hasta que se rompa el cuero" (Until the leather breaks), a fun reggaeton expression for partying as hard as you can, all night long.
