A "Sniffman" or commonly referred to as "A Sniffer" is a person that constantly breathes loudly behind people as a sign of social anxiety or to attract attention to themselves, oftenly someone who will attempt to make you feel sorry for them will not naturally cry immediately, so they rub their eyes and let out the longest 3-pronged sniff they have outward from their nose, usually sounding reminiscent of "Nnnnth,Nntth,Nth", you turn round thinking What the hell was that, and see a "Sniffman" who's eyes are slightly red, you might ask them what's wrong, and they give you a fake lecture on how they have crippling depression
