Unlike a quote or character clip, a thud sound effect is a general impact audio used across memes, gaming edits and short video platforms. These dull hit sounds have been part of film and audio libraries for decades, then became a staple in internet editing because they instantly sell weight, failure or awkward physical comedy. Creators still use them because the sound is short, clear and versatile, fitting everything from slapstick falls to objects hitting the floor without distracting from the joke.
