不知說謂, 不三不四 - Meaning In Context? I have heard 不三不四 pronounced (m sarm m sei) in Cantonese. I wonder if Mandarin speakers use this term and in what context? When I asked, someone they supposed that Mandarin speakers might prefer to use something like


  不知說謂


Which is correct and could anyone supply sample context? Is there a deeper meaning other than the literal sense?

Some one said the phrase is a bit degrading.
不三不四 is a perfectly acceptable term in Mandarin 

Oxford

  1 指人 shady
  
  交不三不四的朋友 
  
  make friends with dubious characters

  2 指言词 neither one thing nor the other
  
  说些不三不四的话 
  
  make frivolous remarks


I think you might be mistaking 不知说谓 for 不知所谓 which 汉语大辞典 defines as:


  不知道该怎么办, 犹言无计可施。


不三不四 is definitely better though!
