Contraction of the words Vagina and Bacteria. Refers to all species and strains of bacteria found in the female anatomical birth opening, the vagina. Vacteria in the normal female adult vagina tend to make the vaginal area acidic by anaerobically breaking down glycogen to release lactic acid, which keeps the vagina healthy. So if dogs are man's best friends, then vacteria are woman's best friends.
I'd totally eat that chick out, but i don't really feel like getting any vacteria in my mouth.

Melanie's got so much vacteria, they've to push out her tampons just to make room.
