The act of discretely inspecting a woman for foul vaginal odor before engaging in intercourse, preformed by hugging her, and slipping the finger in the pussy from behind, then pulling her close (as if to be romantic) placing her head on your shoulder, and the inserted finger to your nose while sniffing without her noticing.
Damn man I was about to pound this bitch out so I did the SNIFF CHECK and she was good to go.

Omg !! I was Messing with this cocola last night and did the sniff check it was putrid! I had to kick her out.

Yo i did the sniff check on this chick and almost threw up! she asked me what was wrong so I stuck my finger up her nose and she gagged!! I told her: this is you!!!!
