A test used to determine the smell of a vagina. You get a little on your finger, give your partner a hug and when they are not looking, you smell your fingers to see if you want to put your mouth there.
"I didn't need to give her the finger test. I could smell it threough her pants."
to reach around a salad dodger and if your fingers dont touch take her home (see going ugly early)
i wanted to pull a chick so i employed the two finger test.
