Birria - goat stew and the broth looks like blood
Canned tuna - the smell, the texture, I can't even swallow it; I choke and almost throw it up
Papaya - the worst fruit I've had so far, the taste blech and it smells like crap (I worked at a supermarket and I thought I stepped in dog poo, but when I turned around I was standing in front of the papayas

)
