When a person who looks like 250 lbs of chewed bubble gum, and thinks they are a fitness expert because they go to Planet Fitness once a week, tells you they are bulking up by eating nothing but trash. The Filthy Bulk is different from the Dirty Bulk is that, in addition to the terrible foods you're consuming, you have a permanent stink that offends every other living creature on earth. These individuals claim that they will eventually go through a cutting phase, but it almost never happens. And when they do lose weight, they still look like a piece of shit. Another annoying habit of this ilk is that they act like fitness experts and look for any ear they can find to tell them about their "healthy" habits.
