Spinach Sarmies and Sausage Sorbet on the Side, Sies!

The A To Z Blog Challenge is plodding along swimmingly.
  

Sies [pronounced, cease] is an Afrikaans Southafricanism meaning an exclamation of something disgusting and vile.  

Similar to "Yuk!" or "Phew" as a response to something vulgar said like "how could you?".  The English South African version is "Sis", which means the same thing. 

If it is directed at a person you 

use it to express your displeasure and disgust towards that person, which basically means "shame on you".

Usage :  "Your feet stink like week-old rotting maggots.  Sies!"

or

"Sis, your April Fools joke made John feel like shite!"
