Worst... Stinky Tofu (tofu that has been in a jar for god knows how long) its a delicacy in China. I swear you can smell it 10 ft away, and the smell alone will make you gag (imagine the fatest, nastiest woman you've ever seen, her not taking a shower for a yr, and your eating her out) NOT EXAGERATING
Close second... Blood pudding (cows blood, rice, can put in other things, wrapped in a sausage skin and cooked)
