"Living a lie" is when a person lies about something so many times, that he actually starts believing in the lie himself.

Very popular among pop-stars, polititians, lawyers, and so on.
"Everybody knows you are just pretending to be brave. Stop livin' a lie! you are a coward, admit it!"

"Maybe others believe in it, but I don't. You don't know how to fight, so stop livin' a lie, saying you are a Karate-master."
