Swack-on 

A Bogan colloquial term, meaning to fight or act in a way that may provoke a fight. Originated in Sydneys outer west where it would be shouted during or before a fight by either the watching party or the belligerent themselves. No one really knows exactly how or why this term was chosen or how it specifically came to be - some believe it may be associated with the onomatopoeia sound for meat being struck with great force or a punch finding its mark. Regardless, its use is relatively widespread across most of Australia as slang, usually within the younger generations along the east coast.

"I saw Corey getting swacked-on by that nasty fucker Tom yesterday." "You wanna Swack-on?!"

double stack on a bun 

When two individuals need to defecate so bad, they use the toilet at the same time. One sits on and a little forward of the first person's lap, and they both relieve themselves.

Crikey, Bruce, I've got to shit so bad we're gonna have to double stack on a bun!

So there I was, minding my own business, when Jane busts into my stall screaming, sits down in my lap, and starts shitting right through my legs. I never thought I'd have a double stack on a bun!
