A dance originating out of Philadelphia, Pennsylvania, preferably, North Philly, by a group of people. The Wu-Tang is a dance for people who actually know how to dance, requiring gyration of hips, and taunting of the opponent.
Be careful when you do the Wu-Tang, because crowds can possibly form around you, and if you do certain moves, you can possibly injure a person.
In my opinion, it's basically battling (breakdancing, etc...) taken to the next level. But it's starting to get on my fuckin nerves, especially when people in their late 20s and 30s all the way up to 50s, know how to Wu-Tang.
The dance has become very popular in the Tri-State area (Pennsylvania, New Jersey, and Delaware), but I don't know if it's spread any farther.
I can't describe the dance, so go to youtube.com and, in the search engine, put in Wu-Tang dance, and there's some videos to show you what the Wu-Tang is (watch a few of them, cuz everybody can't really do the Wu-Tang)
