Harley Quinn debuted in Batman: The Animated Series in 1992, created by Paul Dini and Bruce Timm and voiced by Arleen Sorkin, whose Brooklyn-accented performance made the character an instant fan favourite. Short taunts like this one circulate widely on soundboards and in meme edits, where her voice is as recognisable as the I'm Batman growl from the same universe. The clip endures because it condenses her whole persona, mischievous and mean in equal measure, into a single word that fits any fail.
