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.
