This sound is tied to online Sukuna memes rather than a known line from the anime itself. Sukuna is a major character in Jujutsu Kaisen, and fan communities turned his intimidating design into a recurring thirst joke across short-form edits. Clips like this spread on TikTok, reels and anime meme pages, often alongside rizz sounds or flashy reveal edits. It keeps showing up because the joke is instantly recognizable: taking a feared character and reframing him with exaggerated, unserious attraction for comedic effect.
