Coronó comes from the verb coronar, which literally means "to crown." However, in Mexican slang, especially in the context of urban or street culture, it often means to succeed, achieve a goal, or complete a task, often implying a successful venture or conquest.
In the lyrics, "Pensando y pensando si mi carnal ya coronó / Se fue con una, regresó con dos," the word coronó is used to imply that his friend (carnal) was successful in his romantic or social endeavors, going out with one person and returning with two. This slang usage makes it an interesting and culturally relevant word to learn.
In "MAMI NO," Tito Double P paints a picture of a complicated romance mixed with a life of success and excess. The singer is looking for a woman he calls "Mija," trying to win her back with a bouquet of flowers. He presents an ultimatum: "Are you leaving or staying?" He boasts about his expensive watch and the other women interested in him, yet he admits he's the one who "messed up again" and is desperately trying to call her.
Despite his own flaws and the party lifestyle he shares with his friends, he feels mistreated. He pleads, "I don't deserve for you to treat me like a dog, mami, no." He's completely addicted to her love, comparing her kisses to a drug he'd "inhale all day." The song captures this push-and-pull dynamic: a man living a fast life who, despite his pride, is still waiting for one specific woman to come back to him.
