Is it illigal to make a non direct threat of burning down a college building on Twitter?

What is not-direct about saying that you're close to burning a building down? "Literally" doesn't mean "jokingly" or "hypothetically," it means exactly the opposite. . . "literally" means "for real."

I think most people would get that this is a joke. Unless it was a pattern (with the specific Twitterer or against the college in general), it's unlikely to be taken seriously. However, there could be ramifications, either through the college or legally. Bad idea.
