Arrecho is a piece of Ecuadorian Spanish slang, and this short clip has circulated online as a meme sound for reaction-style videos and short edits. Because the exact original recording is not widely documented, its appeal comes less from a single source than from how recognisable the word feels to Spanish-speaking audiences and how easily its bold tone translates even for listeners who do not speak Spanish. At just over six seconds, it fits the fast pace of short-form content, which helps explain why creators keep reusing it for surprise, frustration and playful exaggeration.
