Saffas

I don't know what it is, maybe this goes on all the time and I haven't noticed yet, but Lordy! do they not take the piss out of the Saffas!
The radio DJ's can do a mean imitation of a Saffa accent.
Up until now I have always thought the Saffa accent was quite inoffensive.
When you hear someone take the piss, it makes the accent sound AWFUL.
I am trying to round my vowels .
This is quite hard to explain. In South Africa, obviously, I didn't even hear the accent .Here, it smacks you in the face. And the Saffas are so LOUD.
Initially, I was somewhat offended, now, I cringe when I hear the DJ's imitate us.
Not too sure what that says about me.
