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!!

Get the Red-box mug.
A phrase to describe a slutty/loosy-goosy girl.

Just like a Red Box movie, she's: cheap, you use her for one night, and then you return her the next day.
Oh that girl last night? Yeah... she was a Red Box girl. Returned her this morning. Actually, cheaper than a Red Box movie, I didn't even have to pay $1!!

A bum that stands next to a red box machine giving you some bullshit sob story and asks for money when all you wanted to do was a rent a couple movies without being bothered. Usually happens in medium to large city or metropolitan areas.
I went to go pick up a couple new movies from the convenience store and this damn red box vulture gave me some stupid story about him and his wife that ran out of gas down the road and was bugging me for money.
