What a great thread! I’m so glad I’m not the only one who loathes coffee. 
In addition to disliking coffee (it’s so bitter!), I dislike beer. When I was a kid, Dad let me try some of his beer. It tasted awful. I said, “You like this stuff?” and left it at that.
Alcohol in general: I’ve never seen the attraction of being drunk.
Popcorn-flavoured jelly beans. I like popcorn itself, but encountering its flavour in sonething with completely the wrong texture makes me want to vomit.
Sushi. I was at university, and was at a friend’s apartment, and this girl I really liked gave me some to try. Never having eaten it, I accepted it and popped it into my mouth–and then almost spit it out again. Vinegar!! Acck!! How can you eat this?
Golf. Also at university, I was introduced to it. I tried to like it, I really did, but its combination of boredom and frustration just doesn’t suit me. “A good walk in the country spoiled”, indeed.
Jazz. Again, I was all prepared to like it and admire its musical intricacy and the skill of its players, and I like the joy of Dixieland, but… in my mind jazz is associated irrevocably with boredom: the boredom of waiting for my parents on formal dinner-party occasions. For my parents, jazz was dinner music.
Tomatoes, whole. When I was a kid I popped a cherry tomato into my mouth under the impression it would be sweet, and got a heck of a shock. I like tomato sauce, just not tomatoes themselves. Like so many of my food dislikes, I think it’s a texture thing.
Shellfish. I’ll take my seafood with the bones on the inside, please.
Things I don’t like, and have never tried to: yappy lap dogs, gangsta rap.
