A certain scientific tool that allows a man (or woman) to measure the horny levels of one particular vagina. Used in a large group setting, the vaginoscope may malfunction, backfiring on the user and creating several black holes. This tool is very rare and very dangerous, so only an exclusive group of highly intelligent asian M.D.PhDs are allowed near them. Some say they don't exist; some haven't the nerve to believe. But some know the truth: it exists, and you can't even tell.
When someone is being a real tool, call them a vaginosarus rex. Which basically means you are a dinosaur's vagina. Best used on your aunt who won't go to dinner with you.
A chronic diseased suffered by men who are pussies. This condition is characterized by build up of sand in the vagina which causes extreme irritability, pussy behavior, and generally acting like a whiny tool. Easily cured with a saline flush, or a bitch slap.
