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!
