Pretty Blood is an independent animated web series whose cute-looking characters, including Rinny, Malino and Copper, appear in dark and exaggerated situations, and this short clip is tagged as Copper's charging shock. Fans lift brief sounds like this from episodes and repost them on soundboards and in fan edits, where a one-second effect is easier to drop into a meme than a longer scene. Its appeal is that instant, recognisable jolt, which works without dialogue and fits any moment that needs a sudden electric hit.
