Serious question. Just pulled some out lol and I got curious.
Shirts/clothing you wear are constantly loosing tiny fibers, which is how you can wear a shirt for a couple years and then it gets patchy and worn thin etc. Obviously the fibers are small and light and get caught on body hair or in crevices. ergo, some of it gets caught in your belly button.
