it was a lady in the grocery store in front of me, the smell just took my breath away and gagged me i could barely stand there behind her without gagging. she was a very large red headed lady when i use to live in Florida, i can still see her face. the smell just overwhelmed me and it seemed that she took forever to check out and leave.
Oh, it was a person. In college, shared an apartment with 3 other guys. One guy did not believe in showers or soap. The smell was soooooo bad!
I went on a hike once to what was supposedly a gorgeous waterfall and river. When I reached that waterfall I immediately started to gag. The smell was so horrible (smelled like rotten eggs and dead animals). The river was filthy! I could even stand by it for like 1 min. I had to start hiking back down because the smell was so horrible!
As a nurse, I'd have to say it's a toss-up between gangrene and burning human flesh. But, personally, the worst smell I've EVER experienced is that British cheese, marmite. Yikes!!!!
