Cocodrilo means "crocodile." While it's a common animal word, its use here is highly specific and culturally revealing.
In the line "De pequeño nunca me llegaba para cocodrilo," Morad isn't talking about a literal reptile. "Cocodrilo" is Spanish street slang for a well-known brand of expensive polo shirt with a crocodile logo (Lacoste). He's sharing a childhood memory of being too poor to afford even a single branded shirt, making this a powerful and authentic window into his past struggles.
Morad's "Mi Barrio" is a proud and honest story about where he comes from. He talks about growing up poor, with lines like "De pequeño nunca me llegaba para cocodrilo" (When I was little I could never afford the crocodile [Lacoste logo]) and having "Parches en rodillas" (Patches on my knees). But even when he was hungry, he says "te juro que no he comido solo" (I swear I haven't eaten alone), showing a deep loyalty to his community. He's not interested in being a fashion model; he bluntly contrasts that world with his own street knowledge, saying "No soy ni modelo... Pero si tú quieres, te enseño a como vestir un kilo" (I'm not a model... But if you want, I'll teach you how to dress a kilo).
This song is his answer to anyone who doubts him or talks about him. He knows people are watching his success, saying "Parece que les molesta, que el Morad sube, sube" (It seems to bother them that Morad is rising, rising). But he doesn't care. He finds his strength and identity in his neighborhood. The chorus is a powerful statement of belonging: "La vida es dura, pero menos en mi barrio" (Life is hard, but less so in my neighborhood). When people ask where he is, the answer is always the same: "¿Dónde está el Morad? Siempre está metido en su barrio" (Where is Morad? He's always in his neighborhood).
