The "private live show" booths at the back of some porn shops and strip clubs, where a girl strips, masturbates, and/or inserts dildos on the lighted side of the glass, while the paying customer jacks off in the dark on the other side of the glass. A few of them are fronts for prostitution or have glory holes, but most are just places for a guy to have a quiet private yank on his crank while a pretty girl shows off to him.
Sandy got tired of guys trying to get under the G-string when they tucked in a bill, so she started working at the slut in a box club.

He didn't have the money for a hooker or even for a rub-and-tug so he ended up going to a slut in a box.

Get the slut in a box mug.
The most powerful version of a "loose" or "woman who gets around" joke. As most people know, the box (cube) is the way to get the most volume for given surface area therefore entitling the highest slut density possible.
Bitch #1: Hey Cory what are you up to.
Cory: Nothing that would concern a Slut in a box like yourself, whore.

Those fat dirty fuckin hoes who work at "The Velvet Touch" on Mt.Morris road right off the exit. Those nasty bitches who sit in a box all day long, dancin and suckin dudes off for quarters.

They are also actually real prostitutes, selling their body in the parking lot.

One of those girls wearing a lame t-shirt to my right.
Get it? She's a slut cause she probably has big jugs, and she's in a box cause the advertisement is a box. Slut in a box.

Get the slut box mug.
Large amps at a party, that people climb up on and start dancing, while the beat and music pump out of the speakers beneath them. Usually a fun, but slutty attention seeking practice aimed to pump up the crowd by shouting the lyrics at them, preferably done after drinking quite a bit of alcohol.
Girl/Guy: I love this song! I'm getting up on the Slut Boxes so everyone can see my moves.
Friend: Wanna see how many people we can get on it?
