He was the first one to join him.
The first one to ever put his trust on him.
Well, sort of. Coby didn't become a pirate, did he?
So basically, he really was the first one to trust Luffy.
To put it bluntly, he was the first in anything, in comparison to anyone else in the crew.
So the second he realizes that Luffy and Nami has this kind of understanding that only the two of them know, he couldn't suppress the tiny nab of jealousy in him.
And Zoro believes he has the right to feel that way.
It should be on a first-come, first-served basis.
He was the first mate.

A/N: I know it might sound so random. But hey. You would have to agree that ZoLu has a standing when it comes to OP pairings.
