And here I am. A Mexican laughing my ass off about this topic. It's just as LiveandSound says. But when it comes to politeness, we try to speak with as much respect as we can muster. For example, if I had to be polite, I'll say:

Honestamente no logro entender.

Now if I was just talking to a friend or some random person, I'll say:

No entendi esto.

It doesn't have to be insulting or anything. We tend to say that when we try to be funny, even in the internet, we do it because it's funny but if we don't have the need of that then we just don't do it.
