Usually occur after a woman has a child (children). Can resemble two sunny-side-up eggs running down a wall, or two watermelons in a downhill race. Not limited by race, ethnicity, or creed. Almost always an unpleasant suprise discovered after the bra comes off. The larger the breasts, the worse the dimay.
My ex wife Amy looked great with her bra on, but when that came off she had national geographic titties!
When a womans boobs sag so bad that her nipples point toward the ground. It kinda remonds you of the days when you would look at the National Geographic Magazines to see the naked Pigmies!!
Dude!! I took off her bra, and these horrid National Geographitits poped out! It kinda ruined the moment!!
