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.

brick stacking

When all of your homies or friends stack on top of eachother until the bottom one dies.

Peter got crushed to death when we were brick stacking in the hallway.

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.

spanking

Procrastinating, often by web surfing online. Goofing off by enjoying yourself instead of getting something done. Refers specifically but not exclusively to masturbating ("spanking the monkey"), especially while looking at porn online.

Am I interrupting?
Nah, just spanking. What's up?
