No no no. Splitting hairs! It means you're making a big deal out of something small. A hair is small, right? So you're going to all this trouble to split it up, which is pointless. So when I said that getting into technicalities was splitting hairs, it had a double meaning. The first was that I was talking about stuff that didn't matter while at the same time literally splitting open an actual hare- a rabbit.

Which, you should know, was hilarious. But you made me explain the joke, so now it's not.
