That space under your knee; the scientific
name is not known. Generally this area does not grow coarse
hair unless you accidentially rub rogaine on it. If such a
thing was done, you'd have a hairy knee-pit.

Girl 2-"Yoh at least your older
brother didnt wipe rogaine
all over it when you were sleeping, my
brother did and now I have a hairy knee pit!"
