I don't mean getting the "ick" about a sexual or romantic partner. And I don't mean being put-off by things that are actually pretty grim. I mean random things that you inexplicably find a bit off-putting in everyday life.
For me, I get a kind of "ick" when I read other people talking about food on forums MN I honestly had no idea why. It's so odd, I really like reading food descriptions in books but in forums I find it really off-putting.
In the real-world, I also really hate opening other people's fridges. They always smell weird (different from my own). I have to hold my breath.
