What is Cock Sniffer?
1.
One who injests the fumes of the penis vigorously through their nostrils, up until the point where the cock gets vacuumed up into their nose, eventually stabbing the sniffers brain until they die a horrible cock-sniffy death.
Detective: I'm sorry Maam. I appears your daughter was killed in a cock-sniffing accident.
Mother: Whats that? Oh sorry, I was sniffing your cock.

the worst of the worst insults...nothing can surpass "cock sniffer." this is the type of person that is so gay that not only would they suck a cock, they would take the time to sniff it too. they enjoy their time down in the groin of another man, and will do anything to stay there. few people are this gay, but there are some out there.
as lorenzo finished sucking off roberto, he took a big sniff of robertos cock.
