Ronjabout is a 3-person pattern that uses the same manipulation sequence as the well-known Roundabout, but with an extra club in the base pattern.
Starting from 7-club two-count, the manipulator substitutes a pass from A to B. A reacts by going into two rounds of 4-count popcorn (either with a triple self or with two heffs), while B does the traditional roundabout exchange with the manipulator. In the end, A passes twice (on 2-count), at which point the new manipulator will be standing in front of them.
The pattern was discovered by Ronja's juggling group, which gave it its name.
