Why is randy orton's move called the RKO?
The RKO has many different definitions and can stand for a lot
of different things - the most-used term is Ruthless Kicking Orton
or even his Initials: Randy Keith Orton.
WWE has no real idea what the RKO stands for. The idea of the
RKO Name was based on his Name, but this idea has merged with the
others.
