How to play bike polo?

Indeed! In my handbook:
Rule no. 247
subrule A.3c

In case of an offensive shuffle ricocheting off the groin area of a defensive player, said defensive player may take possession and call 'straight goal' only after the ball has been handled by another defensive player facing their goal, said defensive player may freely ride to the opponents goal, circle the goal and put the ball in counting for 5 points. 

This play is commonly called a fruit and nut...
