I get the DS/DS/DH etc etc.
I don't tend to use them but as an abbreviation in text, specifically on forums etc, perfectly acceptable.
There is one however which really, really bugs me.
DDog.
Why?
How is this an acronym?
It takes longer (albeit nanoseconds) to type ddog than just plain dog, and quite frankly looks ridiculous.
When I'm reading threads, in my head ddog sounds like d dog. It grates.
Right, now that's off my chest I'm going to a walk FuckingDog (who is most definitely neither dear nor darling!)
