Get a CYS mug for your dad Bob.
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.

Get a CY@ mug for your boyfriend Günter.
A handsome, kind, loving, athletic, and freespirited person, who may not always have the best idea of a good partner.
He spends a lot of time with his female friends, and will do anything to make you laugh. He also has no filter, so he says some pretty random shit.
'Cy is such a cool guy!'

You don't know him, but his name's Cy. He's just the O'Hare delivery guy. He thinks that trees might be worth a try. So he says let it grow.
O'Hare: Let it die, let it die, let it shrivel up and... come on, who's with me, huh?
Marie: Nobody.
Cy: You greedy dirtbag!
