Get the Cy mug.
A gathering of 13-15 year old second generation immigrants (mostly somalian and congolese) who attempt to christen a violent gang facade despite living in the safest city in Canada. Notorious for robbing an apple store where they unloaded bearspray on dozens of innocent bystanders before all belligerents were arrested (and escaped with zero profits). The polar opposite of a true crime organization which glorifies media coverage over actual success in criminal business. A bunch of unsupervised minors that should be shot down in the streets for the dogs that they are. A disgrace to Canadian culture. Also your boy from beaverbrook 6"4 240lb who says cusso all the time made you guys sound so pussy smh.
CYS what a waste of time and a disgrace to true crime organizations. An 80 year old grandpa could lay them out.

CY won the last election with 689 votes from a committee of 1,200 people, which was consisted of people with heavy Mainland China ties.

The election process was heavily criticized as a non-democratic small-circle election. The general public of Hong Kong does not support the election process, the committee, the candidates, or the elect.

CY shall starts his term as the Chief Executive of Hong Kong Special Administrative Region on July 1, 2012.
A: "Do you CY?"
