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.
Guy 1: Where's your girlfriend?
Guy 2: Her and I had box sex last night.
Guy 1: So is she still in the box?
Guy 2: Yeah.
Guy 1: Really? Can I borrow your sex box?
Guy 2: Sure, I don't mind sharing her.

A woman's private parts that are covered in a 5 "o"clock shadow because she hasn't shaved her Muff in a couple days.
Stacy got out of the shower and I seen her shadow box! Tell her to go to the damn store and buy a razor. Her crotch is begining to look like she has Don King in a head lock between her legs.

A box that contains the saved items of past girlfriends, i.e cards or anything they have given you that reminds you of them with the intent of going through it at later date to remember them.
