Actually it's not Spanish! I've done some research, as I, as a native, didn't know about the term either. This is what I got: It's a word from a Nigerian language, and 'Aguanile Mai Mai' is used to call the saint Oggún. Aguan = clean, Ile = house. I hope it helped you!

Firs Check your spanish Acabo de oír la canción de mark anthony se llama "Aguanile". Me gusta mucha perro..<----------perro = dog is (pero) No sé quiere decir.<----No se que quiere decir :-( Que significa " aguanile" It is a Yoruba word (a language of Nigeria West Africa ) In the sauce derived from the Afro - Cuban religion called Santeria .

No es una palabra española, procede de la religion Yoruba y es parte del rezo al Dios Oggún. Saludos.
