"Fuzzy Wuzzy" refers to a lady's private parts. I came across the phrase in Don Delillo's novel Ratner's Star. The young math wiz in the book ask to see a woman's fuzzy wuzzy. I stole a couple of lines from a women's fashion magazine,always a good source for florid and silly descriptions.
Sexy long swetear dresses
Chocolate knee-high leather boots
Maybe tonight will be the night
I can see your fuzzy wuzzy -Dean Wareham from Black Postcards
