When a guy takes off his top and does a breakdance robotic movement in celebration of success, like how Lin Dan of China celebrated after winning his men's singles badminton match against Lee Chong Wei of Malaysia in the semi-finals Thomas Cup 2010.
Especially if he pwned, owned, trashed someone in a game.
1. I hope he won't do the Lin Dance after winning cos he sure will offend some people
2. After winning an excruciating match, he Lin Danced in celebration to the roar of the crowd!
