The 'Unexpected Jihad' meme is a popular bait-and-switch format that originated on Reddit and YouTube around 2014. It typically involves a video that starts with a mundane or innocent premise, only to abruptly cut to an explosion or militant footage paired with a specific Islamic chant known as a Nasheed. The humor stems from the jarring contrast between the initial scene and the sudden, chaotic climax. While it became a staple of 'MLG' era editing and edgy internet humor, it is primarily used to subvert expectations in a way similar to the Rickroll or the 'John Cena' meme. Today, it remains a classic example of high-energy, disruptive digital comedy that plays with timing and shock value.
