Once a once

Posted by Cristina Garat on December 08, 2005

Hi!
I'm translating a play from English into Spanish and at one point one of the characters says:
"...I been a pretty boring kind of a guy actually. I figure I owe it to myself. Once a once."
Can anyone please enlighten me as to the meaning of "once a once"?
Thank you very much for your help!
