Esto va a ser épico is a Spanish phrase meaning this is going to be epic, and as a short sound it circulates mainly as a reaction clip for hype and anticipation online. Its appeal is simple: the words are easy to recognise even for listeners who do not speak Spanish, and the excited delivery makes the meaning clear from tone alone. Creators reuse it across short videos, streams and memes whenever they want to signal that something big, funny or unexpected is about to happen, keeping it popular as a quick, reusable buildup sound.
