Spider-sense is Spider-Man's early-warning ability in Marvel comics and films, alerting Peter Parker to danger before he can see it. Tom Holland's version of the character in the Marvel Cinematic Universe made the sensation a visual and audio shorthand for sudden awareness, with creators lifting the cue for short-form edits and memes. It spread because the sound needs no explanation: audiences already associate it with a hero noticing a threat, so it works as a punchline or tension builder in fan videos, reaction clips and gaming moments.
