Rebolarizando is a playful, made-up word derived from the Portuguese verb rebolar, which means to shake one's hips or buttocks, often in a dance.
In this song, Jojo Maronttinni uses it to describe the act of
"Rebolarizando" is a Brazilian funk party track, and the whole song is one scene: a woman goes out with her friends, walks onto the dance floor, and takes the night over.
The opening lines set her up as unstoppable. She is "pior do que tequila" (worse than tequila), she sets the dance floor alight, and "quando ela baila, tudo para" (when she dances, everything stops). Everyone in the room is watching, and the singers make the point that she already knows it. Nothing here is shy or apologetic.
The hook, "rebolarizando", is a made up word built on "rebolar", which means to shake or swivel your hips. It is not in the dictionary. Turning it into a long, invented gerund is part of the joke, the same way you might say "hip swivelizing" in English. That playfulness is very typical of funk, where a chant only has to be fun to shout back.
Between the choruses the DJs call each other out by name, and the track closes with the full credit roll: DJ Batata, DJ Lindao, Pocahontas and Jojo Todinho. Naming the crew inside the song is standard in this genre. The song is not telling a story with a lesson at the end. It is built to be played loud while people dance, and the lyrics are there to keep the chant going.
For learners, the useful part is the everyday spoken Portuguese: contractions like "'ta" for "esta", the informal "es brutal" as praise rather than criticism, and short punchy sentences that are much closer to how people actually talk than a textbook is.
