Sniff Safe 

1. Any form of a downer kept for the emergency of a bad comedown from cocaine.
2. A fail safe against the comedown off cocaine.

Guy: Chop me out another railski babe, I feel like shit.
Girl: Were all out!
Guy: Thats cool I got a sniff safe, theres a bottle of Zanex and a case of Coors Light downstairs

safety sniff 

Fingering a girl quickly, then smelling your finger to verify if it is safe to go down on her or run for the hills.

Thank God I did a safety sniff, I pulled it out, drug it across my nose and puked right in the bitches face. Had my face been any closer to her diseased hell hole I probably would have drowned on my own puke, what a whore-hound.
