I hated that even as a young child - It really annoys and disgusts me.
My cousin used to do this disgusting thing as a kid where he actually used to scoop his runny snot into his mouth using his fingers as a shovel!
They don't make me physically ill but I do feel repulsion and almost leap in the air if I see a dead bird in front of me in the street. Bit of a phobia maybe.

Sootyj's include.
2 Unclean toilets where one has just eaten.
You eat in unclean toilets?
The smell of cauliflower cheese makes me want to vomit.
Peas are evil.
Other people retching. 
Yeah, that'll do it for me too.
1. Rotting body odour on the London Underground in summertime
2. Public lavatories in airports - who used this seat before me?
3. A pube on a bar of soap
4. A pube on a computer keyboard
5. F**k it - a pube not attached to a pubic area
6. Gym locker rooms and showers
7. The smell of cream soda
8. Stuff rotting in the fridge
9. Cat wee-wee
10. Pouring gloopy out of date milk down the disposal

For me it depends on the colour.

Well let's hope we don't get stuck in a lift together, whilst one of us is feeling sick. It will be an endless hell loop.
Lifts set me off too.
No, not really.

Dirty boy.
