what is the most unpleasant smell?

When the truck comes to pump out the septic tank it's pretty overwhelming. Makes for dry heaving.

When someone puts a banana skin in a waste bucket,closes the cover and it stays there all weekend I just want to gag.

It's a mingling of sweet rotting smell that is just pukifying.

Rotten potatoes. Once I had some mashed potatoes go over in my fridge, and when I opened the container, oh jeez, that was NASTY!! It wasn't like I gagged for a few seconds, then got sick. It was instant sick. Yuck. Really the grossest smell ever (and I've seen-and smelled-dead things-this was worse).

That weird skunk smell you sometimes experience on the road, where it all of a sudden just starts without warning and continues for like five minutes before dissipating. P.U.

Body Odor

Foot Odor

Bad Breath

Skunk Smell

Sulfur

Fish

Pet Urine

many are unpleasant smells, but for me its the smell of egg on a bench or table or on a plate. I just cant stand it.

I got ahold of a piar of dirty hookers. When I went to go downtown on one of 'em the smell was so bad that I blacked out. I was told, that I had fell into a light coma for five days. Later it was reported that the hookers had been arrested for brandashing a deadly weapon! lol

Landfills have the worst smell. They have fecal matter in them, as well as rotting vegetables, meat, diapers, animals, and anything else you can name.

Also, toxic waste disposal sites or treatment sites probably have pretty bad smells too. It's not as bad as landfills, because they have air filters and they trap the toxic vapors in order to protect the workers.

Everyone is way off.

One of the number one worse smells in the world is actually burning human hair.

If you don't believe me, pull out a peice of your hair and (being careful not to set yourself or the house on fire) hold it over a flame and prepare to vomit.

more than once I had to go and save a person who has set themselves on fire..and once you have had the smell of burning flesh of a human being, you never ever can get that smell out of your head....and at times I swear I can still smell the burning flesh..such a terrible smell.I pray to God that no one here ever has to smell it..

Good Luck

God Bless
