Nep is the common nickname for Neptune, the main character of Hyperdimension Neptunia, a Japanese role playing game series that began in 2010 and later expanded into anime and manga adaptations. Short clips of the character's Japanese voice acting circulate online because the performance is instantly recognisable to fans and easy to reuse out of context. This version is shared as a compact game sound, separate from a full scene, and is mainly used by editors and players who want a quick anime reaction without lengthy dialogue or background music.
