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!

on a stack 

You say this when you’re being deadass, but more than deadass. Like someone is being held at gunpoint.

Guy 1: i don’t like you that much
Guy 2: deadass?
Guy 1: no...
Guy 2: haha good joke ma—
Guy 1: on a stack
*Guy 1 murders Guy 2 and effectively reduces his life to nothing but shambles*
