A negative name for the Sex Box 360. I give it this name because it is inferior to the PS3 and sadly to the Nintendo Revolution. Also people partake in this silly machine because they are all followers who can't think for themselves.

When the receiving sexual partner, typically a female, is intentionally put inside a box for sexual purposes. The box is usually shut in such a way that the person inside can't escape without assistance, and there is usually a small air hole and a bigger "Sex Hole" where the vagina/anus is located. A Sex Box is normally used in a situation where a receiving partner wishes to be "used" by multiple people, and the box allows them to both be traded like "property" and allows the person on the outside to "use" him/her without caring about their looks, since all they see is the vagina and/or anus. Some variants include a mouth hole, and more permanent housing.
