Summary
This quote is a humorous and sarcastic way of expressing the speaker's experience of growing up in the entertainment industry. By saying they were "born" at the age of twelve on a MGM lot, the speaker implies that their childhood was replaced and overshadowed by the demands and pressures of working in show business. It conveys a sense of lost innocence and accelerated maturity due to their early initiation into the world of fame and stardom.
