What does the spanish word "inicuo" mean?

what does that word mean. And i dont mean like the dictionary definition, i mean, what does it REALLY mean, like the originality of the word, u know? I belive that it has to have some connection between god and satan because god calls satan and all his doings "inicuo" in the bible(in spanish). and i belive that it means, not equal to god, or not the same, or something like that. So what do you people know?
