What Notes can you not stand ?

Curious to hear what notes in a fragrance are a no for you ?

For me personally, I cannot do Iris. It just reminds me of my wife doing her makeup in the truck & that smell just makes me gag. I traded for a bottle of Prada Lhomme EDT since I thought I liked it from smelling it a few years ago, tried it out and traded it immediately because of the Iris.
