an enhancer that can refer to basically anything at any given time based on the speakers intent. similar to how one would address someone as an "asshole" in a negative regard, but more versatile because it can enhance positive emotion equally. it can demonstrate jealousy, respect, hate, and even happiness. its uses are as wide as the receiver is comfortable with accepting, and generally demands a response. it is derogatory in nature, but a term used amongst friends (especially to each other) to express a given sentiment. originated in south milwaukee, over a game of pool.
