These are some of the things that you should not say in Korean.

ano shipal = fuck off

doltaegari = You've got a big fucking stone head.

Dong = shit

imi shimi pet pojida = your mother has a bald pussy

Jiralhanae = Literally means to become a retarded lunatic.
Note: This word is used to describe someone who is being really strange. It is not too strong a word but it is still very offensive.

jotkara = castration of testicles
Note: This word is usually used by men. Women would not use this word.
