What are Fiber Bars?
Fiber bars are these long square poop sticks that don't really have a taste. Sometimes special brands will one up the game by adding a flavor, but most fiber bars are plain turd rectangles that, as stated above, assist in the action of taking a shit. Fiber bars come in many different shapes and colors, and nobody seems to notice.
People who eat fiber bars usually defacate tons. Usually in the form of string. Their turds usually have odd colors that nobody's seen before. Taking pictures of it would make your camera just fall apart.
