African Firework 

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.

Where you eat your girl out while she's on her period, then proceed to ejaculate into the air, skillfully catching it in your mouth as if it were a Malteaser or other small edible object.

"Hey CJ, does your girl like it when you give her a Strawberry Firework?"

"Yeah man, gotta be careful not to hit yourself in the eye though!"
