Basically a "no contest" plea, but you're not guilty because YOLO!!!
In court, a plea of "Nolo contendere" means that you admit the prosecution has enough evidence to convict you, but
don't admit guilt. "YOLO contendere" is similar, except you have the
excuse that you did it because YOLO! and should thus be set
free.
Judge: You are charged with driving a stolen
BMW into a hotel swimming
pool while high on narcotics. How does the defendant plead?
Millennial: "I plead YOLO contendere. It was wicked fun."
