The unofficial, non-scientific study of the female vagina where males assume to know what a woman's vagina will look, smell, or taste like without prior intimate knowledge.
Someone can also call it a Vaginacologist when they're acting childish.
Eg 1.
1. "Where is she going?"
2. "She's going to the Vaginacologist."
1. "The what?!"
2. "Uhm... The Vaginacologist?"
1. "Uhhm..... Oooooooh! you mean the Gynecologist!!"
2. "Yeah idiot that's totally what I said!"
1. "Uhhh, yeah right."
2. "Thank you"
