The Spider-Man thwip comes from the long-running web-slinging character created for Marvel comics, and the sound became widely recognized through animated series, films and video games.

Its staying power comes from how short and unmistakable it is: one clean burst that instantly signals comic-book action. In meme editing, it often fills the same fast-hit role as a pop sfx.
