Firefly. Only because I've never met anyone that wasn't someone I had to introduce to it. Let alone the comics, novels, board/card games, etc.
But for real, if I ever got anyone enough of a base around me becoming such fans as I; I would also happen to have enough of the old school Mage:tAs books to equate Technocracy with the Alliance and equate the Trads to Pirates.
I have a motorcycle. It's a Harley-Davidson. Immediately, everyone is picturing a large and unpleasant looking bearded man riding a huge, noisy, vibrating, chrome bedazzled air cooled motorcycle without a helmet from one bar to the next.
My harley makes about as much noise as a Toyota Camry. I wear full protective gear when riding it, including a bright and attention-getting helmet. It doesn't get ridden to bars, because drinking interferes with my motorcycle addiction.
The large and unpleasant looking bearded man part is accurate, though.
I never understood the " I'm so badass I'm going to ride without the only thing that can prevent my skull from cracking like an egg" I guess live fast die young, but in the event you don't die the only way we will know where your mouth is, it will be following the feeding tube.
I mean, some dudes won't use environmentally friendly grocery bags because they're afraid to appear "gay". Some men's masculinity is oh so fragile. Like a human skull in a motorcycle accident perhaps.
