He (or she in the most bizzare of cases) who derives sexual pleasure from sniffing saddles. Not to be mistaken for someone obsessed with sniffing shoes, underwear, swimming gear or any upholstry recently occopied by a female - it has to be a saddle! most likely a bicycle or horses saddle. May also be adapted into an insult for a man who is a bit creepy/pervy. Brilliant word altogether!
"dude - that guy over there is sniffing that girls bike saddle and jacking off"
"yeah thats my dad - he's a gronker!!"
