A spell that can accidentally be used when the spell-caster means to use "Rictusempra" (the tickling charm). This spell will cause the target to suffer from sudden, frequent, and uncontrollable bowel movements.
Kira pointed her want at Jake - with the intention of using the tickle charm on him. She mispronounced the incantation and said "RECTUMSEMPRA!!"

Jake quickly rushed to the washroom.
