Tumbao is a vibrant, informal word for a person's unique and captivating way of moving, walking or carrying themselves, often with a rhythmic, confident sway.
In this song, it's used to describe someone's natural charisma, the kind of effortless rhythm and charm that makes a person impossible to ignore on the dance floor.
This song is a high-energy celebration of women from Caracas, Venezuela, affectionately called "Las Caraqueñas." The singers are completely captivated by their walk, their bodies, and their overall presence. They repeatedly mention how these women have a special "tumbao" [swing/rhythm] in their walk that's incredibly attractive.
The lyrics are full of admiration, with lines like "todo está arriba cuando la miro la espalda el cuerpo" [everything is up when I look at her back, her body] and "se me paran los pelos como camino de las telarañas" [my hairs stand on end like the path of spiderwebs] when describing their captivating movement. The song also playfully suggests that these women are so enchanting, they might even "engañan" [deceive] you! It's a lively and passionate ode to the unique charm and beauty of Las Caraqueñas, making you want to get up and dance along with their irresistible rhythm.
