"ABC, Taxiing runway 18 for a departure to the South"
This is not even close to correct. I understand the main point was the taxiing, not taxis, but since when are you supposed to say 'for a departure to the south'? Same thing with the SARWATCH call as pointed out earlier.
I think the OP should concentrate on what they are doing and keep the radio turned up, no matter how frustrating.
My company, like many others, put a strong emphasis on getting the radio calls right, as it is a show of pressessionalism, not only for yourself, but the company you represent.
