I read something similar some time ago and posted about it. This is from a Russian study stating that the shape of your butt can reveal your personality. See if this is true for you or someone you know.

Men with Muscle Butts are: Strong, persistent and enduring in bed.

Women with Round Butts are: Sexually active, materialistic and unkind.

Those With Wrinkly Butts are: Reliable, steady and calm, whereas asymmetrical wrinkles expose selfish and greedy people.

Those Who Have Saddlebag Butts are: Faithful in love and marriage. Men and women with such buttocks are hopelessly mediocre individuals.

Women With Saggy Butt Butts are: Good wives and careful mothers

Those With Hairy Butts are: very kind and agreeable people, although they also expose thier genetic predisposition to illnesses of pelvic organs, first and foremost. One should also bear in mind the fact that parents , who have hairy buttocks, give birth to psychologically unbalanced, short-tempered children.

The combination of red hair on the head and black hair on the buttocks may occur for talented and highly emotional people. Grey bottom hair is a vestige of premature impotence of men, whereas red hair reveals their depraved nature.
