"Moms_Bang_Teens_42.mp4" is a prominent "bait-and-switch" internet meme from the late 2000s and early 2010s that used an explicit title to trick viewers, only to play a low-quality, loud, and nonsensical video instead. Serving as a "Rickroll"-style prank, the file-name-based deception relied on curiosity to embarrass users, often incorporating the number 42 as a nod to The Hitchhiker's Guide to the Galaxy .
