Nowadays I read some articles about Busan grammar but I still want to know the big differences between Busan Dialect and Seoul Dialect (especially in speaking). What makes Korean people said that Busan dialect so 'funny' or 'weird'? Is Busan dialect sound so (sorry) 'plebeian'?

 (I ask about this because I'm foreigner. I want to know the answer from Korean people). Thank you very much.)
