There is no widely documented origin for this short Spanish phrase, so it is best understood as an internet reaction clip rather than a line from a known film or show. Its appeal comes from its simplicity: a single, relatable complaint about a sister that needs no translation of the feeling, even for listeners who only catch the tone. Shared in memes, edits and short videos, it has survived because sibling frustration is universal, and the three-second length makes it easy to drop into almost any comedic moment.
