Abbreviation of Port Coquitlam, a smaller city on the outskirts of Vancouver. PoCo is infamous for being a rough almost Compton like suburb and also it is where mass murderer/ pig farmer Willy Pickton lived. PoCo was a nice place in the 70's and 80's when its population first started to grow and it was also the hometown of Canadian hero; Terry Fox.
