The muhehehe laugh is a classic cartoon-villain trope, used online as a shorthand for scheming, plotting and playful mischief rather than a quote from one specific film or show. Short villain laughs circulate widely on meme soundboards and in short-form videos, where creators reuse them as reaction sounds for pranks, reveals and tongue-in-cheek evil plans. Its appeal is its instant readability: even without context, listeners hear cunning intent. Similar laughing clips, such as a baby laughing meme, show how a single laugh can carry a whole joke.
