The act of getting the shits, then proceeding to defecate into a condom. Once this has happened you give the condom to your partner and tell them to blow into it thus expanding the condom and causing it to explode sending bits of shits in every direction but for the majority, the face of the blower.
Also works with any other bodily fluid.
Ex. Cum, Gooch Gravy, Pussy Juice etc.
Joe: Dude, I heard Matt gave Madeline a African Firework last night.
Zac: That is one shitty mess... literally.
