In “Mi Loca,” Los Rumberos turn an unstable romance into a funny kind of emotional crisis. The singer has spent more money than he earned and still cannot understand why her interest has disappeared: he feels “pasé de moda en tu cama” [I went out of fashion in your bed]. He wants direction, asking “¿A dónde vamos?” [Where are we going?], but she gives him none. One day she says she loves him, and the next she does not even acknowledge him. In this context, “no me topas” means “you do not notice me” or “you act as if I am not there.” Her “rumba” means her party-loving way of living, and he admits that it hurts him.
The singer is so confused that he tries almost everything for an answer: a horoscope, a psychologist, tarot cards, a temazcal, and ayahuasca, even though he says he did not believe in those things before. That list makes the situation sound both desperate and wonderfully excessive. He keeps returning to the line “Me está volviendo loco que seas tan loca” [You are driving me crazy by being so crazy], while her kisses remain just as unpredictable: “Hoy dices que me quieres, mañana ni me topas” [Today you say you love me, tomorrow you do not even notice me]. “Mi loca” means “my crazy girl,” an affectionate nickname for the woman who keeps taking away his kisses in the playful refrain: “mi loquita me lo quita” [my little crazy girl takes it away from me].
