The term used to describe the trashy teenagers/young adults (and possibly older) who live in Gatineau, Quebec. Like many suburban teens, they have resorted to being oh-so ghetto and live the thug life, despite the fact they live in good households in the most economically stable area of Canada. The girls wear too much make-up and dress slutty. The guys have the gangsta look going. Both act like morons and are violent for no good reason, instead of doing anything respectable with their lives. They are often seen ruining fun nights in the clubs of Hull.
Guy 1: What is going on here on Portage? This place is full of angry boys and desperate girls!

Guy 2: Looks like the Gat Trash is out in full force tonight..
