A bout of diarrhea that, when released in a public bathroom, is so particularly smelly and loud that passers-by may mistake it for a terrorist attack.
Person A: Dude, who are those federal agent looking guys wearing sunglasses down in the lobby? I just saw them put Ken in the back of one of their vehicles.
Person B: You won’t believe it – Ken had a bad case of al-qaedarrhea in the first floor bathroom. Some poor soul using the stall next to him freaked when he heard and smelt it, and called the Dept. of Homeland Security.
