At Gary Con and Gamehole Con for that matter, after a few too many beers, you might just see a:
Hodag -- a mythical animal reported chiefly from Wisconsin and Minnesota, noted for its ugliness, lateral horns, and hooked tail, and reputed to be outstanding in both ferocity and melancholy.
I first came across this word while at Gary Con actually. I was in the bar and talking to someone about Wisconsin. I think they were from up in northern Wisconsin and they mentioned Hodag. I couldn't tell if they were putting me on, or if I were drunk. Likely both, but they swore they were real. And it would be cool if they are. I love Wisconsin, it's a really cool state. Hope to see it (and perhaps a few Hodag as well) in March!
