Various contractions of "Ka Ni Na Bu Chao Chee Bye". The rudest phrase of all. Use only if you wish to be beaten up or want other people to think you were raised in a longkang. Literally: "Fuck your mother/Fuck your mother's smelly cunt." Usually used in Singapore.
Na beh, do you have a problem with me?
