It sounds like you're describing a fragrance or scent profile. The description mentions fresh açai berries covered in dark chocolate, cold rice milk, and white musk. Initially, the scent resembles the chocolate, akin to Hershey's, as opposed to a smoother chocolate like Dove. As it dries down, a sharp and clean note, likely the white musk, becomes more prominent. The end result is a lingering scent reminiscent of wet chocolate. Fragrances can evoke various sensory experiences and memories, and it seems like this one captures the essence of chocolate and other elements in a unique way.
