Kevin "Bloody" Wilson is a legend in Australian comedy. He does't push the envelope -- he tears it up, sets it on fire, and then urinates on it, to put it out.
Smutty (and as politically incorrect) as he may be, he really waxes lyrical with a lot of his stuff. Being filthy and outrageous could be considered a cheap grab for laughs, but he manages to take it to a new level.
The backstory to this song isn't mentioned in this clip, but is explained in the original release of the recording, which was done at a live gig. He was trying to get an 'R' rating for his upcoming show at the Montreal Comedy Festival, and got told it would be granted, as long as he didn't say "cunt." That was out of bounds, even for an R rating... so, he wrote this song. You can't say cunt in Canada! Enjoy!
