This sound comes from Hentai (DJ Edit) by S3RL, an Australian happy hardcore producer known for fast electronic tracks with anime-influenced styling. Short excerpts from the song spread in meme edits, anime compilations and reposted short videos, where the title and high-energy vibe made it an easy fit for "sussy" jokes. It still gets used because the clip is instantly recognizable, exaggerated and playful, similar to how creators reuse other anime meme sounds like onii-chan for awkward or suggestive punchlines.
