Double Stacking

When someone sits on the toilet and another person sits on their lap to shit and uses their thighs as a seat.

Tony was shitting and Sam needed to as well, so Sam sat on Tony and used double stacking to shit.

shacking

Lying on some type of furniture, preferably of a futon nature. Usually two females, or one male and one female. Involving talking, bonding, and much fun but on an entirely platonic level. Powwowing is an exceptable activity while shacking.

*NB. Usually only possible by males of a mature personality. Females do not have these kinds of issues.

Hey wanna shack tonight? Sure, let's go hit the futizzle. I need a break from these exams.
