anyone who speaks Spanish care to explain this song to me?

[QueBert]

linky I speak limited Spanish, I know Mas Maiz means More Corn in English. But what the hell are they talking about? I'm guessing it's some sort of slang. I've been listening to this song for years now and still am clueless what the fuck it's about. I guess the beat has kept me listening. Maybe it's just a pointless club song and really is about Corn but I'd like to know lol

for all you rap haters, it's a rap/reggaeton song.
