The curb scene from American History X was indeed pretty disturbed. Though I think the worst I've seen is the bit from that one movie (I think it's Brain Dead) where the old zombie lady pops a zit/cyst and the puss ends up in the guys custard - after which he procedes to eat it. It's not as much the scene specifically but rather the whole idea that utterly revolts me.
Hostel, as has been said a lot, has nothing on that, to me. The problem with it was that it was so overdone I could literally only laugh at the cheesy special effects. When I watched part one and came to the eyeball cutting part I simply couldn't take it seriously and kept thinking that the girl looked like she had pizza all over her face. Lulz ensued as everybody else in the room completely grossed out.
