From am mathematical point of view, if one draws straight lines from the center of the erect nipples through the boobs those lines will cross eachother at some point (in the above case the playboy point)
or if the nipples orientation deviated from eachother those lines will never meet eachother in the same plane but one has to create a helpline between those two lines. How longer the helpline gets how more deviated those nipples are towards eachother. If the nipples are not deviated one has a perfect isosceles triangle in al other cases its a scalene triangle.
Because of diversity in erect nipple orientation (if alone by gravity) one gets all sort of mathematical traingles and angles, which are on itself meaningless and statistically all possible, but knowing what sexistic pigs man is one could make a plastic religion out of it as it is reported by any mens magazine.
This is just a mathematical observation of me, it has nothing to do with breastcancer according to google-glass. But if your nipples line up with the moon in conjunction with jupiter and when mars is retrograde in the house of pluto then perhaps...
