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."
