WTF BOOM! is a vintage internet meme that dates back to the early 2000s, primarily popularized on platforms like Newgrounds and YouTube. The meme typically features a short clip or a series of images leading up to a sudden, deafening explosion accompanied by a voice shouting 'WTF... BOOM!'. It became a staple of 'earrape' humor and shock videos, used to surprise viewers during otherwise quiet moments. Often paired with countdowns or unexpected accidents, it serves as a high-energy punchline that represents sudden chaos or overwhelming failure. Its lasting appeal lies in its simplicity and the universal humor found in high-volume, slapstick-style destruction.
