Interestingly enough, "biffin" is also a little-known
Australian slang-word for the
perineum, the bit of - for lack of a better term -
squiggly skin between your
anus and your
genitals. I first learned it when a friend of mine recited this song...
Between your balls and your bum is your biffin,
It's a place where you shouldn't be sniffin'...Charming, no? This friend's father is a
gyno, so he has plenty of other little gems of wisdom concerning all manner of interesting, obscure areas of the
anogenital region.
As you can imagine, I was quite shocked when I learned biffin was also an apple treat. No so tasty anymore, ey, kiddies?
