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!?

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.

A idiot who repeatedly sniffs knob, they also become addicted to the smell, a knob sniff is of the male sex.
The more extremists put the knob up their nose and sniffs till the cum fires up his nose.

Chris: no being a knob sniff doesnt mean you loose your virginity, you've had more pricks than a second hand dart board
