I’ll start with the fact that I kind of like the smell of gasoline,

That is not nearly unpopular.

For me, pure Isopropyl alcohol (as in not part of some product). Reminds me of doctor's office when I was a kid, and I like it.

I'm not a fan of the "new car smell", for some reason. The "new computer smell", on the other hand, is a rare treat.

Cologne or perfume on a human. Stop. It's not nice, I don't want to smell you.

Spent gunpowder smells absolutely lovely.

While not particularly good, it's not bad either: I'm immune to the smell of cow dung. Pig, sheep, horse, etc smell horrible. But Cow shit is perfectly OK. Guess which animal I grew up with.

Perfumes and air fresheners. They all smell like toxic chemicals to me.

New car smell, it's awful. Sort of stale plastic if I were to describe it.

Amplified by long trips on bad roads as kid. Guaranteed to make you feel like vomiting on some sections. Now when I anticipate/pack for a trip I tend to smell that again even though I'm not even in a car.

Literally anything that smells like seafood will make me nauseous

Cat piss does not smell particularly bad to me.

Maybe it's toxoplasma speaking.

I love the smell of bleach.

Absolutely hate the stench of coffee. About the only thing worse is coffee with vanilla in it. Disgusting.

Lavender. It's too strong

I hate the smell of raw brown sugar. I like it in foods, and it's fine cooked, but the raw smell makes me gag.

Lavender because of garbage bags. Scented garbage bags are awful.

The smell of the freshly mown lawn. It smells so bad and I'm allergic so I guess this explains why I dislike how it smells.

I like the smell of moldy houses. I've been told it's a health hazard, so I don't engage or encourage it, but when people excuse the smell in their residence, I tell them I like it.

I love the smell of wood burning/camp fire smell. There's something I find comforting about it. I've yet to find a candle that exactly replicates the smell, but if I ever do, I'm buying 50.

Motor oil is a smell that I really like. It's from growing up around mechanic shops, I think.

I hate the smell of sandalwood. It's just overwhelming and I can't get past the heaviness of it. My coworkers use a tobacco and sandalwood scented room spray and I want to gag every time.

I know some people like the after rain smell but I despise it. Makes me think Im surrounded by dead worms

Cooking oil.

I love me some fried food; I get nauseated smelling the oil itself while things are cooking though. It's worse depending on the oil or fats used. Straight butter and eggs frying in a pan is the worst.

I do janitorial work at McDonald's in the mornings and I always wait until after the switch to lunch to really clean the kitchen because the smell of the eggs being fried makes me wanna puke.

Dislike lavender. I once passed through a town that produces a lot of lavender, has a festival for it and everything. It was so awful. Lovely area, though.

Pool water, I really like the smell of it.

I love the smell of alfalfa, I even have scent modifiers in the scent. People think I'm crazy (not that they don't already).

The smell of diesel and 2stroke mix are nostalgic for me.

Also I love the smell of vinegar.

Vinegar smell makes me want to vomit and it's used in every fecking fish n chips place. blergh

fresh printed business cards from an actual printing press, with ink.

I can‘t stand the smell of coffee roasting since childhood… hated it when one of my employer moved office next to a coffee rostery

Same for the gasoline. It's not as uncommon to like it as you might think
