sniff test 

When you are about to eat pussy, you slowly go down for the alls clear at the belly button. If you can get that far and it doesn't smell bad, you can safely proceed. If there is a stench, you can slowly work yourself back up and shove your dick/or pussy back in her mouth.

I performed the sniff test on Gina and she was all roses.

Sniff Test 

When a girl sniffs a guys junk to see if he's been fuckin around with someone else before he came home. If she smells vag, he's guilty as charged.

Girl: Get over here and drop your pants.
Guy arriving home after "working late": Shit, are you giving me a sniff test?
Girl: Youve been fuckin some other chick again havent you!?

sniff test 

Similar to definition #1, but instead used to determine whether milk is safe to use. The sniff test is again largely used by students or others that only occasionally go to the shop.

Shit, I went to baste my pie but the milk's off. If only I'd done the sniff test then I wouldn't have to wash my pie.

dip n' sniff test 

The process of putting a finger in a girl's vagina then subtly bringing the finger up to your nose and smelling it. Is done in order to determine if the girl smells good enough to go down on.

Thank god I used the dip n' sniff test on that girl I brought home last night. My finger smelled like I dipped it in the frylator at Red Lobster! Needless to say, my face went no where near that pussy.
