refers to playing the campaign mode of a video game (such as "Call of Duty" or "Halo") strictly to exclude someone who seeks to play online with others.

Can be expanded to describe any form of exclusion.
Richard: You guys are playing campaign mode just to exclude me!

Mike: No we're not!

Mike (in a private chat with another player): We totally are.
