I disagree, SHB. I think our friend "The big croc" here must have seen Crocodile (the character) - via spoiler from Oda somewhere - before she met up with Iva-chan and got herself turned into the "he" as we know of him now. So technically, he has a woman crush, which is normal for a guy.

And I think the word "big" in his nick refers to the bosom that Crocodile once had.
