The clip is associated with Harley Quinn, whose playful and unpredictable personality makes the mouse pun a natural fit for her character. Shared as a short audio snippet, it has circulated among meme creators who use it to introduce animals, new characters or themselves with a joke built into the greeting. Its appeal comes from the simplicity of the wordplay: the pun is clear in a few seconds, easy to place over a reveal and instantly understood without context. That combination has kept it in regular use for lighthearted edits, pet videos and character introductions.
