Others have done a good job answering this question, but I'd like to add one possible exception. I think that you're saying that it sounds a bit peculiar – but that doesn't make it wrong. Sometimes such word pairings are used for dramatic or comedic effect.
In this case, I've heard this device used when someone wants to emphasize the mediocrity of something:
That was absolutely satisfactory.
When spoken, the listener typically expects a strong word to come after absolutely, such as fantastic or outstanding. When a more neutral word comes out instead, it catches the listener by surprise, which can be somewhat comical, if used in the right context.
One place I might use this is after going to a restaurant. Let's say the food was decent – but not great; the service was marginal – but not rude; the prices were a little high – but not outlandish. All told, the evening was a bit of a disappointment, but not a catastrophe. I didn't have a terrible time, but I'm unlikely to revisit the establishment.
On the way home, my companion asks, "So, what did you think?"
I might respond, "Oh, it was absolutely decent," with a heavy emphasis on absolutely, particularly if I'm catching the vibe that my companion was equally unimpressed. At hearing absolutely, my friend might begin to wonder if I had a very different feeling, only to realize that, no, we both feel the same way after all.
