That's a very reasonable suggestion, with a very reasonable function. Therefore it fails my test.

Just kidding. There is no such test. And I'm sticking to that story.

Here's the Wikipedia entry on Purple Prose:

purple prose is used to describe passages, or sometimes entire literary works, written in prose so overly extravagant, ornate or flowery as to break the flow and draw attention to itself.

I was thinking Blovinator could do that in a more insidious sense, perhaps. But having a faux-practical function like that would be hilarious.
