A few days back, there was talk that 'Dilly Dilly' was included on a list of phrases that were banned from the Masters this weekend. If anyone shouted them during play, security would immediately kick them out.
Now, the site SkratchTV claims that they have the full, 'official list' of phrases banned at Augusta. It's so ridiculous that it's almost surely a joke, but so is the idea that they would specifically BAN anyone from saying 'Dilly Dilly,' so who knows. The fact that it doesn't include "GET IN THE HOLE!" basically proves it's a satirical list. By the way, even though there were rumors that there was some sort of list of banned phrases, we don't know that for sure.
And it seems strange that they'd ban particular phrases, as opposed to the act of shouting to disrupt the golfers, because ultimately, why does it matter?
Here's the supposed "official list."
