What's the worse thing your flatulence has smelled like?

Like a dead cat rolled in baby shit and thrown into a tire fire.

My gas once smelled liked pizza after I hate a whole large pizza pie. It wasn't the worst smell, but it was definitely the most bizarre.

Roses :D

OMG I love these comments. LMAO.

I'm a chick, but I can admit it... at times mine don't smell or don't smell much, but other times it's like sulfur AND/OR raw sewage!

Warning: TMI
One night I was constantly woken by this pervasive smell of death and poison. It was getting into my dreams and I spent the entire night trying to figure out in my sleep whether it was purely a figment of my dreams, a rat had died in a vent, or the apacolypse had just transpired outside my window.

Rotting corpses

McDonalds.

I don't fart. Never have, never will.

I don't know, but do NOT ever eat anything with chicory in it like Fiber One bars...that shit gives you horrible gas and diarrhea.

Rotten eggs/sulfur.

Once I overheard a young boy say "That's a Green Potsy!"
His friend inquired "What's that?" The boy responded with "That's the worst fart you can blow!"

I remember this clearly and took it as a sign of wisdom from the 8-10 year-olds. Of course, I only heard that snippet of information and was glad I wasn't there for the Green Potsy event.

I have made and probably surpassed the register on this one.
You will know intrinsically when you have Green Potsy.

Burning rubber

Lol it's hard to say... Not because I don't fart or they are scentless. But I usually like the smell of mine, so I may be not impartial enough :D

People say that these rotten eggs ones that burn your nose are the worst... But I personally don't think so, although I have those too. For me worse to handle are these sour farts, that smell like fermenting trash or something. Yuck! :(

You know the smell when you first open a bag of potato chips? like that.

My Mom's Turkey stuffing

Me, mom, and Dad were riding in pickup cab. Dads driving. Dad farted, Mom acused me. I protested of course! It wasn't me! That fart smells like someone's does after eating at "Ryan's Restauraunt" then she chewed me out for being the most discussing person on earth for being able to identify where someone had eaten by the smell of their farts! Well, I asked, where did you eat before you picked me up? She said, We did eat at Ryan's! But your still discussing for knowing that by the smell of a fart!

Mix of a very foul, spoiled shit and semen

Shit.

I had food poisoning twice in a week, I was not well.. nearly hospitalised.

Let's just say it didn't smell nice.
