Howzit my bru? Talk like a South African

I was on trek in my bakkie to the dorp where my Cherry lives. My bokkie needed muti for a mozzie bite. I had to stop at the robot and a bergie with damaged takkies offered me a boerewors. I thought aikona, is he doff?! I’d like to have a lekker sammie. I said sorry my China, now now. Something further on the way I bought a biltong, but there was a miggie on there. My bru is a fundi in braaien, I called him and he said “ag man, izzit? I’m just jolling in my cozzie”. No braai just now.
