Why does Smith call the Oracle mom?

[Annuit Coeptis]

In the last movie just before Smith overwrites himself to the oracle he says this:


Agent Smith/Sati: Cookies need love like everything does.
Oracle: You are a *******, you know that?
AgentSmith: You would know, Mom.


Why does Smith call the oracle mom? I have read some explanations on other parts of the internet but they seem like kind of a stretch.

I believe it's actually a simple answer. She's the mother of the Matrix. He was probably being sarcastic. Either that, or she wrote him. But I kind of doubt that.

As defined in the 2nd movie in the scene with the Architect, the Architect is the father of the matrix and the Oracle is the mother. I doubt that the Oracle would have created Smith, because even then it's more likely the Architect made him. That would actually have been a mild but interesting twist if the Architect created Smith :o
