Which Korean dishes are typically hottest? For the typical palate of most people from English-speaking countries, just about all Korean food is spicy.

But for those of us who love hot spicy food, I want to know if there are certain specific meals in Korean cuisine which generally have the reputation of being the hottest.

For comparison I know I have Mexican friends that think certain Mexican dishes are too hot for them. Are there some Korean dishes that even some Koreans avoid for being "too spicy"?
I found ojingeo bokkeum (오징어볶음), which is squid stir-fried in a chilli sauce, to be pretty intense, especially as a jeongol (전골) or stew, where it's both hot (as in spicy) and hot (as in temperature). The sweetness of the stew does nothing to lessen the intensity of the dish.

Also ridiculously spicy is buldak (불닭), which is again a stir-fry of chicken in a chilli sauce, with tteok (떡) or rice cake.
