What Is The Bumfluff That I Find Lurking In My Belly Button ??

Question

What Is It And Whats It Made of ??

How Does It Get There??

Answer 1

Bumfluff?

Bumfluff is pubic hair found around the buttcrack (obviously) and chin, which is where the term came from.

It's just cloth fibres from your t-shirt - the result of the skin around your belly button tightening and compressing when you bend over, or simply put your feet up.
