When you have your bottom machine installing drivers and you are fucking up your top machine. - Linus Sebastian

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!

This is a maneuver that requires both a male and female, excluding guy on guy since it will require an unobstructed anus. this however does not exclude girl on girl if a strap-on is readily available. This act starts off with the man(or the man in the relationship) sitting on the toilet facing the tank, and then the reciever mounting the the male. after starting intrecourse the female then procedes to shit which on most occasions will leave a trail of fecal matter on the scrotum.
"man i cant believe that girl did a michigan moose track double stack with me last night, and she wasn't even that drunk either!"
