I prefer "breasteses"
I laud the idea of bloggers baring their breasts for charity and cancer awareness. Sainted Wyff would agree that I am what would be called a "breast man." However, just as Andrea Harris despises the usage "coming with?" or "going with?", I despise the word "booby" when used for a woman's breast.

Tits, please. Or hoots. Or a rack. Boobies sounds, umm, undignified.
