Red box is basically a giant red box at grocery stores and mcdonalds restaurants were you can rent movies for a cheap price.
Red box also can refer to a very severe sexually transmitted disease (STD) for women.
I dont want to buy a movie, lets go down to Micky D's and rent a movie from the Red Box.
Damn, did you hear Sandra got Red-Box from going to that party last weekend. Who knows what and who she did!!
