One of my classmates got his "black belt". He has an extremely cocky attitude. Congratulated him out of politeness.
Later saw a video one of his friends (yes, he has friends) and it was horrible!
His sparring was bad and he kept on doing high level kicks (like hook kick) and only landed one. He didn't use his hands and his guard was pitifully low.
He also kept on bouncing up and down and looked like a bunny.
The thing that ticks me off the most is that he still thinks he's "all that" after everyone saw the video.
