Doritos (makes me want to hurl when someone opens a bag of them and especially when I can smell it on someone's breath)
Burnt popcorn (the teacher down the hall loves it and burns it in her microwave for snack)
Subway - the smell clings to you after you leave--smells like stinky armpits
most perfumes, anything really powdery/old lady like Chanel or spicy ones
mold and mildew
Wet dog and even regular doggie smell
New car smell
When you first walk in Target
Burnt rubber like from a vacuum cleaner belt - I always smell it at work --nasty!!
Yankee Candle--I get a sinus heachache walking past the store
I'm sure I can go on....
Oh yeah, any type of fish or seafood --- I hate when DH orders seafood and I have to eat my own food and breathe his in
When I was in college, people would make (and sometimes burn) popcorn in the common room's microwave. Sometimes the popcorn would burn and that would set off the smoke alarm. The smoke alarm would force us to go outside.
Then when it was clear to come back inside, we were greeted with that smell.
