Dip and Sniff 

The experiment a man uses before sex, in which he sticks his fingers inside the female's vagina, and proceeds to sniff it, to confirm that she does not have a smelly or diseased vagina.

Guy: "Dude you shouldn't have gone in raw..."

Guy 2: "Don't worry, it was safe, I did the Dip and Sniff test."

The Dip and Sniff 

If you like one night stands and you love goin down on girls you need to do this, we've all gotten that nasty surprise of a manky minge so what ya do is kiss her while you drop the hand or "dip" your fingers in her vag to tickle her belly button from the inside, after you've been down there for a few minutes bring your hand up to the side of her neck and then kiss her neck while you have a little "sniff" of your fingers, if they smell good go for it if not just stay away my friend

Dude i hope you dip and sniffed that girl last night she looked dirty (The Dip and Sniff)
