Wasted in the most extreme sense of the word. When one becomes filthy wasted he/she will do and say things that they would never dream of doing sober. You will also admit to things that you are ashamed of! Girls will want to slap bitches and then make out with 'em and guys will want to kill a nigga!
"I have never seen Allie get that filthy wasted! She even admitted to the time she let John put it in her ass!"
