High Quality Content by WIKIPEDIA articles! Evil laughter or maniacal laughter is a stock manic laughter by a villain in fiction. In comic books, where supervillains utter such laughs, it is variously rendered as mwahahaha, muwhahaha, muahahaha, buahahaha, etc. (Compared to Ho ho ho). These words are also commonly used on internet Blogs, Bulletin board systems, and games. There, they are generally used when some form of victory is attained, or to indicate superiority over someone else. The words are often used as either interjections or less frequently, as nouns. An evil laugh is often entertaining for friends because each one may be unique.
