Literally meaning something like what a peculiar pleasure, the phrase works as a wry Spanish reaction to moments that are odd, uncomfortable or unexpectedly appealing. It circulates as a short reaction clip on soundboards and in meme edits, where its brevity makes it easy to drop over a clip without interrupting the action. Because the wording is unusual and slightly formal, it stands out from louder reaction sounds, and creators keep returning to it for dry, understated humour rather than an obvious punchline.
