In Texas Hold'em, you can fold your hand and throw your cards into the "muck". Now imagine someone does that to a mom. Pretty messed up.

McKean 

A small town in Erie County that sometimes you just wonder why it even exists. It’s located not far from Fairview and most of the people that live in McKean are either depressed or elderly. There is no stores in McKean, if you wanna go to Walmart you have to drive 20 minutes to Edinboro. They have the best fucking pizza though called McKean Pizza. In McKean traffic lights don’t exist, all they have is Stop signs which people rarely ever stop at.

I went to McKean and it was depressing as hell.
