Top Definition
A sexual situation involving anal beads. After inserting the beads into the woman's anus, the man then yanks them out, causing the woman to defecate uncontrollably. Both the man and woman then start to roll in the shit, like jack and Jill rolling down the hill. Sometimes, this happens on accident.
Joe: "...and then we just started to roll in it."

Mike: "Awwww! The jack and Jill cannonblast!"
