Often mistaken with anal fluff (different thing etirely)... After a period of certain unhygienically living, a small amount of dust, cat hairs (dog hairs. human hair.. whatever) and sweat congeals in the belly button area of the body and stays there until one either washes (thus terminating the period of unhygienically living and smell) or the lucky other half (or embarassed and soon to fail one night stand) picks it out and unvariably smells it.... it smells of bum.
Phwoar! your bum fluf smells of ass!
What's fluff? Oh! It smells of bottoms. Must be bum fluff again.

Originating from leprechaun rectums in south ireland, bum fluff is the fibres of sweaty underwear that sticks to the scrotum and "Batty criece" when a respectable amount of sweat has been produced that day. On a hot day, people may be seen pulling their underwear out of the arse with their hands, this usually occurs when bum fluff is present.
"Ooh it's hot today isn't it?" *pulls underwear from bum crack*
