Definition
An oath of sincerity that invokes the sacred 2006 Pixar masterpiece 'Cars' instead of the Almighty. Because apparently, Lightning McQueen is the new deity for Gen-Z truthfulness, making "on god" look positively antiquated. Ka-chow your way to credibility.
Example Usage
"Bro, I actually studied for the exam this time." "On Cars?" "On Cars."
