10th lobby 

A tenth prestige lobby is where a hacker/haxor creates a private match where a mod menu is displayed, commonly containing a feature where you can convert from whatever level you are, to 10th or 11th Prestige Level 70. It also can give you an aimbot, wallhacks, all challenges, all titles and emblems and a modded name/clan tag. You need ISO mods or a Jtag to do the lobby. A Jtag is a cable used to use modding software on your Xbox 360/Playstation 3. Also what every Modern Warfare 2 has regretted getting into.

10th Prestige Lobby

A game in Modern Warfare 2, Call of Duty 4, or Call of Duty 5 in which the player can reach the very last prestige in the game, 10th prestige. When in the lobby, if you get a kill, instead of the display saying "+10" or "+50" it says "+1.986E+0.006". In this lobby, you can also unlock challenges, camoflauges, and the hidden spinning skull emblem. You normally have to pay $10 (7 UK pounds) to get in, but some are also free...

Dude I was getting so much XP in that 10th prestige lobby last night!
