A technique used mostly by women to limit the sound of their turds entering the toilet water. A wad of toilet paper is held underneath their ass with one hand while they hover slightly above or lean forward off of the toilet seat. By bouncing their turd off of the cushy paper, the turd slides into the water in silence.
"Damn honey, the bathroom at your parents house is so close to the kitchen, I had to do some backboarding to avoid disrupting breakfast."
"Woops, my wrist is covered in poo... I guess I need to practice my backboarding skills."
While there is evidence that some of the 62,000 people sent to Australia came willingly, and signed contracts to work on the plantations, many others mostly Pacific Islanders were lured or taken forcibly onto the boats.
This practice is what's known as blackbirding.
Blackbirding - technical indentured labourers are blackbirds.
