Madison Bumgarner has a terrible nickname.
Seriously. "MadBum". That's the sort of thing you expect to hear attached to a minor character in a Monty Python skit, or maybe used as an insult when the Gallagher boys from Oasis are feuding again. It doesn't even fit into the sort of pre-fab model of modern baseball nicknames, where you either add a "-sey" to a guy's last name, or take his first initial and the first syllable of his last name and get something that I'm pretty much started out as an internet "What's Your Porn Star Name?" meme.
