lint and other material that has collected in the belly button of a hairy chested male. the lint is then rolled into a ball and is given as a gift to others who he knows will appreciate the thought that you put into it. sometimes force is required for the beneficiary to appreciate the gift and how much sweat and time was needed to make it.
Man 1: I have a present for you Gunnar.
Man 2: OH NOES! NOT BELLY BEANS!
