After having sex with a male or female (whatever that person is into), You crap in the condom, poke a hole in the bottom and drain out the remaining seman. You then place the "poo bomb" into your hand and hurl it at an un-suspecting person's face. Preferably when they are talking so it lands in the person's mouth.
