You know what I just figured out?
In the context of "NSW, Australia," NSW stands for New South Wales.
I totally thought it meant "Not Safe for Work" and that all you Australian slashers were warning people about NC17 content. And placing the warning in your location rather than bio, for reasons which I assumed had something to do with being insane Australians.
This is very similar to the time I suddenly realized that Clearly Canadians come from CANADA. (No shit. I looked on the bottle and it said "Made in Canada" and I was like WTF OMG CANADA!?!?!)
