I know that Lost had mentioned once about changing the voice menu, at least I think he did.
Well I remember a moment in Half Life 2, when you are about to enter the citadel, Barney yells "and tell Dr. Breen i said FUCK YOU!"
that moment is censored due to an in game SLAM of a metal gate, but the file itself is not. I would love to have to option to just say "F*** YOU" to other players in game
