An area of your office that pretends to be "busy-busy" working, when in actuality only catching up on Facebook and Myspace, making their weekly sporting picks, analyzing their fantasy football teams, and shopping online for Manpons (see manpon.) The productive area of the office, known as the "Engine Room" completes the majority of the work - however - the Slack-Arena is quick to take credit for this work.
A slack-arena is made up of multiple slackerinos - see slackerino
"The Slack-Arena at my office is 50% of the employees but probably only actually completes 25% of the work!"
