Fetor
Finally! A word I've actually used in my own writing. Sure, I've only done it once, but it still counts. Let's get right down to business.
fe·tor also foe·tor [fē-tər] n. an offensive stale or putrid odour; stench
Synonyms: malodor, malodour, reek, stench, stink, mephitis
Etymology: “offensive smell,” mid-15c., from L. fetor, foetor, from fetere (see fetid).
This one ended up so short! Oh well, it's Friday. Have a great weekend, everybody.
