For those of us who don't have enough things about our body to obsess over, The Frisky has kindly clued us in to sternomancy -- the art of reading boobs.

According to this ancient frat boy Spanish science (ahem), the shape of a woman's rack reveals the personality traits she'll exhibit in the sack. So educated men can divine important insights, like that girls with round boobs will try anything in bed and the triangle-boobed like to dominate.

While we think this is a pretty funny story to pass around with your friends, we're hardly worried about guys overanalyzing your bra contents. Every guy who's gotten close enough to our boobs to determine their sternomanical shape has been too grateful to pass judgment.

Check it out and let us know in the comments if you think they've read your rack right.
