I think this is the problem. In you world, who you chose to talk to and read it might have made perfect sense.
But the titles on FWR threads are not just for your friends and how you talk to each other, and not just those who post on FWR.
I know nobody who talks about ferrets, so why use an obscure phrase?
And as to reading reddit why would I?
Again incomprehensible to think that because that is what you do, that is what every body does.
Just like those who keep posting links to X when 99.9% of the population isn't on X and more importantly cant read anything that's posted.
I know many of us have a shorthand way of talking to people we know or are friends. But this is the internet.
So the likelihood that what is common to my life or how I chat to friends and family, is going to instantly have the same meaning to thousand if not millions of stranges, is very remote.
