I start a full beard every October 1, so it's not really a playoff beard. The weird thing (relatively) that I do is eat Smarties candies during tense points in playoff games. This started back in 2000 and I typically nervously eat them piece by piece during the later innings. I don't eat Smarties at any other time in my life...but now, I don't watch a playoff game without them. I will also be wearing my Mets cap and jersey, which I rarely wear at other times unless attending games. I'm likely to be drinking some of the New Glarus Octoberfest beer as well.
