When someone calls you a sandbox they are referring to the term "son of a beach", and the son of a beach is probably a sandbox. So, they are pretty much calling you a little bitch. Tell it to your friends.

Often a result from a long day at the beach, a sandbox results from an excessive amount of sand in the box. Other causes may be from mud restling or as a result of a hot new trend. In Europe, women often throw sand in their box in the case of a hot sexual encounter. One can often tell when a girl has a sandbox because when she walks it makes a crunching/grinding sound.
