I'll be honest: I don't have a good justification for bringing this up. I could craft one. I could talk about the creative formation of compound modifiers and how hyphens help the reader understand more quickly which words are modifying which. I could talk about language trends in recent years in which such compounds are used to craft insults.
But the truth is, I just remembered a "Simpsons" line and it's making me smile.
The setup: Some Canadians and some Americans are hurling insults back and forth at each other. The line in question came from one of the Canadians. He called the Americans a bunch of "Shatner-stealing Mexico touchers."
Really, did I need to find a way to justify sharing that line? I didn't think so.
