THE DIRTY ARMY:Nik, Urban Dictionary defines ratchet like this: adj. a term for someone who is either 1. a whore 2. dirty/nasty 3. ghetto as HELL 4. being annoying 5. busted. Meet: Erin Wallace and Dave Guertin, they are the definition of ratchet and make Ottawa look bad. Erin lost her virginity to Dave when she was 12 and he was 14. She got pregnant somewhere along the way and he dumped her ass. Then he went to prison for 3 years for armed robbery and 9 months before he was going to be released he asked her out.. and SHE SAID YES. Oh, I forgot to mention that during their separation she had a baby with someone else and is still in a custody battle. They live together in disgusting community housing in Sandy Hill. She thinks she is the hottest shit but she is a fat, nasty SLOO and he thinks he’s all that but he is the dirt under my shoe and dirty dirty dirty. He just got out two months ago and already he cybered with some chick on facebook, and cheated on Erin multiple times. She is a delusional piece of crap and he just needs someone to use as a cum dumpster and a place to live since he got out. This is seriously the dirtiest most ratchet couple in all of Ottawa. Disgusting.
