Lileks analyzes expressions of horror and disgust

He prioritizes them:

I think the order of things is this:

Augh > oy > feh > meh

I respectfully disagree. Augh=eeewww, the feeling you get when you find a dog turd on your shoe; oy expresses the tragic condition of man;* feh is the proper locution when you avoid stepping on the dog turd; and meh=amused rejection.

*Often oy vey or oy, veyzmir.
