The lingo or slang used to refer to a room, or bedroom who's specific purpose is for video games mainly XBOX 360. It is not uncommon for a garage to be turned into a command center. Layout consists of 2-3 couches, and a few armchairs, a coffee table, multiple ash trays, neon beer signs, rugs, pillows, a refrigirator, game/movie posters and anything else neccessary for long-term gaming. (curtains to block out windows, no clocks, etc.)
When Call of Duty World at War came out, my friends and I gathered in the command center and no-lifed it for a couple of days.
