The greatest and largest weekly rave venue ever to hit Los Angeles in the late 90's thru 2001 venue in San Bernadino, CA. With 3 areas in Trance, Hardcore, and Drum N Bass. This venue was large enough to accomadate 3-4000 people weekly for over 20 months strong. If ever there was a rave venue that could pack week after week regarless of the show, it was The Masterdome.

Masterlooser15

The best badass coder out there, who actually knows how to program in different coding languages, and even knows how to maintain his own cheat, x88Cheats! The best cheat out there which can easily win against anyone in a hvh.

When you call someone a MasterLooser15, you are telling them that they are a god at being a programmer.

Friend: "Hey Dude, look how good he is at programming!"
Me: "Whoa! He MUST be a masterlooser15."
