Which state in Malaysia, has the worst dialect?

define WORST.

there's no bad dialect in malaysia, each is unique.

im kelantanese, i understand Terengganu, northen, KL, Indo slang, @ a bit of negeri sembilan & melaka.

All but Sarawak & Sabah. Sorry to say that BM dialect in west malaysia are all mixed up & rough. The original proper & smoothness of speaking BM dialect comes from Indonesia and East Malaysians adopted in very well.

i don't find any of the dialect to be worst. in fact i love them, even though i do not understand some, kelantanese for example..

but my favorite is sarawakian malay. :)

every dialect is unique, i'm very proud to speak in my dialect

plzz. dont say kelantan,...

emmm.... ^_^ Kelantan and Negeri sembilan , its hard to understand Kelantanese . :D

kelantan i guess. can't understand them whenever they talk in their state dialect.lol

sarawak... wow they talk sometimes so fast it feels like bullet... n then when i say pardon please they speak even faster..

but why you have question!
