Can't stand corn fructose and palm sugar based snacks. Terrible everything - engironmental impact, texture, health impact, flavor. It's just the cheapest possible option that ruins everything it touches.

Peeps. I've never like marshmallow anything, really, and definitely not those abominations. Most cinnamon-flavored things. Edit: forgot one: chocolate-covered cherries. I don't know why. I have a cherry tree and will eat the cherries off it and don't even mind most artificially-cheery-flavored things. I also eat other fruits covered in chocolate (even durian).

Swede here.

Some American candy, mostly bad chocolate

The cheap no name "chocolates" that taste like eating oil solids disguised as chocolate

Hands down absolutely nothing worse than peeps. They somehow manage to make twizzlers taste like ultra gourmet candy.

There is this brittle thing of foam everyone likes to make into weird shapes like little birds... I don't know what it is called and I don't want too

I tried Hershey's (American chocolate) before and it tasted absolutely disgusting. it will never ever come remotely close to Dairy Milk or Galaxy

Twizzlers.

I tried them in the US and it just felt like I was chewing on a piece of plastic.

On the other hand, unlike most of the people in the comments, I love licorice.

The Harry Potter bean things which has awful flavors mixed in, like puke etc.

Probably these little lychee candy things I had years ago. No fruit flavor at all. Tasted as though someone mixed powdered blackboard chalk and sugar.

Chocolate brandy beans.

They always seem to be made with cheapest shittiest chocolate as well but that brandy liqueurs inside is revolting enough on its own thread the chocolate is usually completely forgettable

The disgusting Harry Potter every flavour beans. They had jelly belly jelly beans that tasted like dirt, grass, booger, vomit, ear wax, and others I can't remember.

I haven't actually tried this but my friend did.

The red gum that's just pure cinnamon or something. Plus it's spicy. Ew. Just ew

Hersheys "chocolate". I spit it out, and a bit embarrassed, asked "could it gone bad during the flight?"

Well, obviously this stuff does taste like vomit, and Americans seem to be OK with that. Explains a lot about American behavior. If chocolate here would taste like that, we probably would have more mass shootings, too.

Salted liquorice.

I had a Norwegian friend who waxed lyrical about this stuff. So when I saw it for the first time in a shop, I grabbed a packet to nibble on while waiting for my train.

Plain black liquorice is delicious and salt makes everything taste better, and the Norwegian seemed like a nice, relatively normal person who enjoyed other things I liked. This was a low risk choice of mid morning snack, I thought to myself.

I was wrong. So very wrong.

This stuff tastes like it was peeled off the bottom of a shoe after walking through the city all day. It's not salt either, it's freaking ammonium chloride.

To paraphrase the Wikipedia:

The mineral is commonly formed on burning coal dumps from condensation of coal-derived gases. It is also found around some types of volcanic vents. It is a product of the reaction of hydrochloric acid and ammonia.

And Scandi's put this on liquorice and like it. Even the kids. Madness. It took my all not to heave into a bin after trying it and like six cups of black tea to get the taste out of my mouth.

I gave the Norwegian the rest of the packet and he laughed at me while I watched him eat it because I looked so horrified.

I tried some matcha mochi once. It didn't really taste good, but the worst thing about it was that it was just boring.
