Lagnasium
Refering to an area in an online community where lag becomes an understatement.
The certain game released for xbox 360 and pc which was hoping to ride off the success of Elder Scrolls 4: Oblivion, except it had the addition of online play, can only be described as a Lagnasium in both single player and online play and was not even close to making a 100th percent of what Oblivion did.
