Definition of "bumfluff"

He still had bumfluff on his cheeks, he was that young. About once a month he used to shave it off, and come skiting about it. I smiled at the memory of him all lathered up, grinning at me through the mirror as he went to work on the bumfluff.

Dad'd kill me for doing this. It's so obvious that I mustn't touch his shaver, he's never even told me not to. […] His shaver came closer to the bumfluff on my upper lip ... closer ... It bit me! I unplugged it. Oh God. Now my bumfluff had a ridiculous patch missing.

Sometimes the post-pubertal life stage of a young male figure is indicated by the appearance on his cheeks of ‘bum fluff’ or an incipient beard. […] The pictorial context would, therefore, suggest that the representation of ‘bum fluff’ on the cheeks of a male youth usually indicates that he has passed beyond the limits of minority status and has already reached at least his eighteenth year when in civic, legal, military and social terms he was accorded new roles and responsibilities not appropriate to the status of those who were still paides, or boys.

There was me, Eddie, Wilco and a guy called Bobby Thomlinson who we never went around with much because he wore a lot of crushed velvet and had bumfluff. Our thinking was he could get the tickets because, thanks to the bumfluff on his face, he looked much, much older than the fourteen-years-old that he was.

There was no way I was twenty-one. I looked nineteen at a push. Maybe sixteen-and-a-half, which is what I was. Big though – not fat – but tall. No baby-face and no bum-fluff moustache. The fisher boys had their bum-fluff moustaches and they looked total pricks.
