What's the worst scent you've ever smelled?

[InbetweenDreams]

Grease Dumpster at Wendy's.
I worked there when i was in highschool, when the grill buckets got full we would take them out back and dump them in the grease dumpster. Old rotten grease with chuncks of hamburger, a few drowned rats that found their way into the dumpster and couldn't get out along with other unfavorable's that thought they wanted to eat the grease and or scavenge the dead bodies.

And for whatever reason that old grease had a way of clinging to you (at least the smell) *even if you didnt touch it* I remember coming home washing and re washing my uniform and STILL put your nose to it and you could smell it! Thank god, never again!

Yep I remember that...pretty rancid stuff.

I hate the smell of burning hair...ugh gagging.

Many of the things people mentioned, bad breath... Rotten food.. Really hard to say which is the worst they're all pretty damn bad lol
