When an adolescent boy first grows facial hair it looks all wispy and yucky. This hair resembles the fluffy hair on some people's bums. So shave it off or you can look ridiculous. Girls really hate it. I'm a girl!

So shave it off and get a REAL beard started!
Once I was up close to my big brother's friend. He had heaps of Bum Fluff on his face which made me want to PUKE!

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.

In gaming terms, Bumfluff would be the term used for cheaters. People who are shite and need cheats so they can win.
