When someone is not even worthy of kissing your ass they may be invited to sniff your hoop as that is the closest they are going to get.
Can also be a hand gesture while driving for example: making a "hoop" with thumb and forefinger tips together brought up tip the nasal cavity and a healthy deep breath.

So then, we do the slap 'n' sniff, so he slaps me with his dick and I smell it. Then we do the swordfighting.

To give you a tryout or try to figure out what it's all about. A more civilized form of what a dog does when it...uh...sniffs your ass.
Bill: "Ooh...looks like Peter messed up on his TPS reports again. We may need to fire him."
Bob: "Peter's a bright kid, I like his style. Let's send him out to the Boston office and let those guys sniff his ass for a couple of weeks. If they don't like what they see, then we'll can the bastard."
Stan: "Peter, why don't you come out to Boston and let us sniff your ass for a little bit? Not trying to scare you, but Bill would like us to evaluate your performance."
Peter: "Man, you guys are such a bunch of brown-nosers."

To get access to or obtain the privelage of having relations with a beautiful woman. To ask for approval or acceptance from a friend or colleague when obtaining something of personal value or worth.
While sitting at the bar two attractive women approached my friends and I. As they approached, Tyrone asked the tall lady with the apple bottom, "What does it take for a playa like me to get a sniff?"
A business deal is underway and a personal friend of one of the men in the deal enters the room. After hearing what is being discussed, he asks, "give me a sniff" with some of that action.

When you walk in to a toilet cubicle at work realising someone else has just been there and you can only hold your breath for so long.
The First Sniff of Death is that first breath.

Buddy: "You look a bit pale. Everything ok?"
Me: "I went to the can and realised too late that Colin had just been in before me. The First Sniff of Death melted my sinuses and have permanently damaged my nostrils and lungs".
