Slackground 

When you're slacking off in an office setting that requires a computer and have a window up for display purposes to simulate work. Often requires Alt+tab to display your Slackground when browsing non-work related content.

For example: Spread Sheets, Important looking emails, Memos, ect.

Oh crap Boss Roger just walked by! Good thing I had my Slackground displayed so he did not see the NSFW pictures I was looking at.

Person 1: My black friends and I went to see a movie last night.

Person 2: That's cool. How was it?

blackground 

When you see an black actor put in the background of a TV show or commercial merely as a token or to fulfill a quota.

This commercial could use some blackground. Someone grab the head shots and see who we can put back there.

Blackground Check 

The act of checking your surroundings for any black people prior to making a potentially insulting racist joke and getting beaten. Usually the joker will state they are making the check out loud, much to the hilarity of those familiar with the term.

Johnny: So this black guy walks into a bar... Wait, gotta do a blackground check....

Tim: Oh, that. LOL.

Johnny: Nope, no can do, there's one over there.

Blackground 

More common in the southern states, such as Georgia, Florida, and Tennesee, The Blackground is the area in the back of a school bus or regular city bus(or even trains and subways) where blacks often congregate, in can also be the front of these vehicles. Not out of segregation, but by choice, the blacks often group together, especially teens. They generally cause shenanigans to occur. Resulting in:

Why white people don't like black people that much.

Busdriver: Go sit in the back, theres no seats up front!

White Boy: But I dont wanna go in the blackground!!!

Busdriver: too bad sunny.

Black Girl: My weave is loose!
