I don't know in the sentence I will refer to, what does "Lance Armstrong your way" mean, is there any irony or not? The situation is between a man and a woman, and the man wants to deny a mistake he had made. Her friend had heard a sentence which the man had said, and then the woman says:
She was in the other room, you bastard! In the next room, ok, so don't try and Lance Armstrong your way outta this one!
