Mostly well-known as a major brand of fireworks. In a classic episode of "Reno 911", the two black cops, Officers Jones and Williams go to the home of a weird hippie who is stockpiling fireworks that are illegal.

So Officer Jones picks up a package of Black Cat fireworks, saying "You know Black Cat's are illegal in the state of Nevada." The hippie responds with "You guys are a couple of black cats."
My friend accidently shot me in the face with some Black Cats. So I accidently smashed his face with my fist.

A person who does not fit in to any group. The strong silent type, always observing and analyzing situations before getting involved. May have a lot to say but does not say it. Often settles problems alone and is more than capable of it. For the few who get to know him/her a close and loyal friend they will find. A black cat is a nomad, forever roaming the world. A black cat may seem shy to some but make no mistake, he/she is merely bored and is thinking of greater things. Black cats are not judgemental and are easy to confide in. A beloved friend, though not always around. They may not understand your affection toward them, but will always return friendship. A black cat is extremely good at figuring people out, as a result black cats fall in love easy after accepting all your faults and your trust. They can fall for more than one person resulting in bad luck. When a black cat is your lover only death can keep you apart, but not for long. The person you want to cross paths with, The perfect lover and loyal best friend, a black cat roaming.
