To digress in an extensive way. To divert the conversation to a topic that is not only unrelated to the topic at hand, but a topic that will likely have no immediate resolution either.
That's an interesting discussion, but let's stay on track and not go down a rat-hole.

Made famous by the TWIT podcast Macbreak Weekly, a rat hole is when a discussion follows a constant tangent and ends up with a topic that has nothing to do with the original discussion.
That discussion of Macs which changed into a discussion of classical music was quite the rat hole.

A topic of conversation that has diverted wildly from the original conversational thread and is generally viewed by all (but the one leading the topic) as being without resolution, or at the very least is uninteresting to others in the group. Ratholes usually open up when related but tangential topics are discussed which are explored in much more detail than is required for the relational reference to the original thread.
I was trying to keep things on topic, but you've opened up a big rathole with all this talk of comic book plot twists.
