Diss in Code

"SHAVE YOUR ARMPITS YOU TROLLOP!!"

The young man's voice yelled at me from a passing car.
I was wearing a sleeveless dress but it was after sunset so he couldn't have possibly seen my armpits.
And if he had he'd have seen they were shaved.

So I wondered if perhaps this was Brisbane code for "Get a car or get off the road you greenie hippy cyclist."
