Not in person but read about a fat woman stuck to a toilet while her husband kept bringing her food. Walking down a sidewalk one day behind a huge fat woman I smelled something foul like a dead dog, rotten fish and cat shit as I was slow walking behind this creature. No way to pass. After a minute I realized the odor was getting stronger the closer I got and then made a detour to get out of her wake. Instantly that reek vanished but the nausea took about half an hour to leave. It was like mind just couldn't let it go. Disgusting! The smell was so thick I felt like it stuck to me. I went home, took a shower and put on fresh clothes.
