“Shark” is a term that originated from poker. A shark is a term used to describe a player with a tight- aggressive play style. This means that they fold the majority of their hands, but when they do play a hand, they usually make big, well placed bets. Most sharks are very good players.

Unlike some of the retarded, sexually related definitions on UrbanDictionary, this is the real meaning. A sea animal completely misunderstood because of the terror that Jaws brought. When they attack you, it's mainly because they misinterpret you as a seal (their eyesight is poor), and they rarely kill anyone. Tigers and elephants kill 200 people a year...sharks: 7. Yet people continue to save up for "Save the Elephant/Tiger" funds.

Sharks are sometimes hunted with huge, 60 miles lines. They get caught in the liens and since they can't move their gills to breath, they suffocate. Dolphins/seals also get caught in these nets, and cannot resurface for air.

They're used for shark soup, which is thought to be good luck. Yet it causes bloodshed for sea creatures. Why would this be good luck..?
Instead of writing a retarded sexually related definition, I've decided to supply you with something you can actually use, since most people who write stupid things on UrbanDictionary are 12 year old virgins and will never get the chance to try out the sexual moves written on other definitions.
