Debbie and I decided to make a name for a type of acro we like. Rolling sequences include a lot of catherines wheels, F2H, H2H, shoulder stands, sometimes whips and pops. They stay in a vertical plane, often moving from l-base to standing and back. People ask me why I call them Ralphs. It is because I am constantly naming things and trying to come up with names which somehow signify the move. I got tired of all this contrived meaning one day so I made a completely random name.
