I'm having a disagreement about how to treat a compound descriptor like "This is one of those everyone-shut-up-and-go-away kind of days."
It has been claimed to me that this descriptor can just as well be italicized, like so:
"This is one of those everyone shut up and go away kind of days."
I have not been able to find any evidence for this, and I don't recall seeing it myself.
Can anyone provide a source that advocates for italics? I've had trouble looking this up because most entries on compound words only deal with the kind that has two words ("blue-green dress"), and those are always hyphenated, not italicized.
[Edit] The claim comes from a writer who disagreed with my correction of her work, and insisted that italicizing the phrase is just as correct. My subsequent inquiries have uncovered that this usage can be found in certain fiction novels (I haven't read them, but friends mentioned this to me), which leads me to guess that it's a result of poor editing and not an accepted usage. As these kinds of things do sometimes get taken up, it may one day be seen as the "correct" way [see the modern use of "artful" to mean "artistic"]. However, since no one has brought forth any convincing argument or source for the usage, at present I believe it's simply incorrect.
