'lo everybody, gathering some opinions on fair use. Now, I know fair use depends largely on a ton of factors, one of which is the amount of the original production you're using. (For instance, using one line in a song is vastly riskier than using one line from a movie.) Another is use in satire. And sometimes it all comes down to a specific court, because I don't think there's any hard-and-fast rule about fair use. I have two questionable things in my story, both done as comedy and so I hope it falls under satire. One is a part in which I have a Constructicon (from Transformers), described as "purple and green robot," appear and say one snippet of dialog in a two-sentence paragraph. The words "Constructicons" and "Devastator" are used, so there's no ambiguity here. It's a quick in and out, and the punchline of the scene is it's unexpected and has no further context. Is this considered too risky? Is this considered sitting on the fence? Should I change the reference? Would I be okay by just eliminating the use of the names and just having the character obvious by description? Second is I say "You deserve a break today" in reference to Kit Kat. Kit Kat is named, so again, no ambiguity. Should I eliminate the line? Thanks all! Again, I know all people can offer are opinions or experiences on fair use, but let's hear 'em.
