Often heard in the order "badda bing, badda boom", the phrase is a way of saying, "That's it, it's all taken care of". The exact origin of "badda boom, badda bing" is a mystery, but the best guess I've heard is that it started as a verbal imitation of a "rim shot," the drummer's punctuation to a comic's punchline in the old vaudeville routines.
"We set the Judge up with a hooker, Louie busts in with a camera, and badda bing, badda boom, case dismissed".
A person who enjoys lifes greatest pleasures with a certain charm and swagger envied by most. A Bad cat can be, but is not limited to someone who is rich and famous. If you are walking or driving along the street and see someone dressed unconventionally or they are wearing a top hat, fedora, feathered cap, or cowboy hat, chances are they are a bad cat. If someone accomplishes something good, they themselves are a badcat, even if only for a short while. To "cat someone" is also to beat them or trick them, or make them look stupid while making yourself look good.
n. An extremely negative demeanor; a bad attitude. Usually directed at someone who is being unusually disrespectful and hurtful, instead of appropriately sarcastic and cynical. See also hater.
