This sound is associated with Hollow Ichigo from Bleach and is commonly shared in anime soundboards and short-form edits as a sinister laugh. Fans use it to signal possession, madness or a sudden shift into a more dangerous mood. It stays popular because the voice is instantly recognizable to Bleach viewers and still works even for people who only know it as a creepy anime reaction sound. Online, it often appears in AMVs, villain edits and exaggerated comeback clips.
