Alebrestran comes from the regional Mexican verb alebrestar, meaning to stir up, excite, or make someone restless and rowdy.
In the lyric "con corridos se alebrestan", the singer boasts that the party-goers instantly get wild when the corridos start playing. It’s a vivid, slangy word that perfectly captures the high-energy vibe of the song and isn’t something you’ll find in everyday Spanish textbooks.
This song is a perfect example of the Corrido Tumbado lifestyle. Fuerza Regida kicks things off by shrugging off a breakup in the most confident way possible. He's not sad about it, he's just moving on. He tells his ex, "Tú ya andas con otro, ni modo, qué pena" (You're with someone else now, oh well, what a shame). He follows it up with one of the most blunt lines ever: "Sí estás bonita y todo, pero hay más culos que estrellas" (Yeah you're pretty and all, but there are more asses than stars). It's his way of saying there are plenty of other women out there for him.
From there, the song becomes a celebration of living a life of excess while waiting for the right person to come along. He sings, "Y mientras llega mi persona favorita / Seguiré con mi loquera, los excesos, las morritas" (And while my favorite person arrives / I'll continue with my craziness, the excesses, the girls). It's all about popping bottles, spending big stacks of cash, and partying with his friends. He describes his life as being like a movie, shouting "Prendan luces, cámaras y acción" (Turn on the lights, cameras, and action) because he's living like an artist, surrounded by beautiful women.
