Rolling thunder is a classic weather and suspense sound effect rather than a quote tied to one character or viral clip. Online, long thunder rumbles like this are commonly used in meme edits, horror videos, and dramatic reaction posts because they instantly signal danger, tension, or an overblown serious moment. Its staying power comes from how recognizable the sound is: viewers immediately understand the mood change. It is often paired with other exaggerated impact sounds such as the vine boom sound in short-form edits.
