Frontea comes from the verb frontear, which means to "show off" or "brag." It's a common slang term in Spanish-speaking urban music, particularly in the Canary Islands where Quevedo is from.
In the song, Quevedo uses it to describe how his sisters and girlfriend "frontean" (show off) about their connection to him, highlighting his success and the pride his loved ones take in it. It's a culturally relevant word that offers insight into modern Spanish slang.
In "AHORA QUÉ," Quevedo takes a moment to reflect on his incredibly fast rise to fame. He describes his life as a "regalo" (gift) and feels like everything is happening so quickly it gives him "vértigo" (dizziness). He looks back on the hard work and sacrifice, remembering when it was just him and a few friends working on their music. Now, he's a global star, a hit from his home island of Gran Canaria to the rest of the world.
Despite his success, Quevedo stays grounded by what truly matters. He shouts out the friends and collaborators who were with him from the beginning, saying he'll never forget those who supported him "cuando no había nada" (when there was nothing). The most important thing to him is his family's well-being. He finds joy in knowing his parents are calm and proudly mentions how his sisters and girlfriend "frontea" (show off) about their connection to him. For Quevedo, money and fancy cars aren't the goal; the real prize is seeing his loved ones happy and knowing his hard work paid off.
