Aneurysm is a Nirvana song first released as the B-side to Smells Like Teen Spirit in 1991 and later included on the compilation Incesticide in 1992, with Kurt Cobain on vocals. The track is known for its loud-quiet dynamics and raw, shouted choruses, which make short vocal moments easy to lift for reaction clips. On soundboards and in short-form edits, the aha works as a compact piece of 1990s grunge attitude, recognisable even to listeners who do not know the full song.
