The phrase comes from everyday Spanish, where 'hijos de perra' works as a coarse plural insult, roughly like calling a group sons of a bitch. This stretched upload became popular as a shareable reaction clip rather than as a quote tied to a confirmed film, show or creator. Its appeal online is the spelling-defying delivery, with extra s letters matching the hiss people hear. It now circulates in meme edits, gaming chats and short videos wherever an exaggerated Spanish curse fits a sudden loss, prank or betrayal better than a calm reaction would.
