No puede ser is an everyday Spanish expression meaning it cannot be, and the stretched seeer version spread online as a short reaction clip in meme edits and soundboards. Users cut it into videos where someone discovers a betrayal, a mistake or an absurd coincidence, letting the Spanish delivery carry the shock even for viewers who do not speak the language. Its role is close to an Emotional Damage Meme or an Oh My God Meme, a single line that instantly turns disbelief into comedy and keeps being reused.
