There are several kinds of Fecal jihaddists.
1: The Roadside Bomber a.k.a. Land Miner
This skillful but sick asshole shits on the ground or floor, it can be anywhere, indoors or outdoors, even in the middle of a five-star restaurant He's like a dog. He wants you to step in it. These guys are usually passive-aggressive cowards; some though just have a sick but excellent sense of humor.
2: The Phantom Menace (or Phantom Shitter)
This guy is similar The Roadside Bomber but he's not quite as dangerous. This individual tends to shit in places where they linger, like a hallway closet or under a bed. People who upper deck are Phantom Menaces.
3: The Suicide Bomber
This is the most unholy of the bunch. This individual will defecate in his or her own pants and keep it there for everyone to bask in. Suicide Bombers often dunch themselves in public and go to places like the food court in the local mall for about two hours while smelling like a shit.
Host: Thanks, but what do you mean by fecal jihad?
Partygoer: Someone made a poopy on your kitchen floor and a few people tracked it though the house.
