To be drunk way past the point of good sense and decision making, usually leads to blacking out on ping pong tables or throwing up all over the place and forgetting to clean it up. It's the level of drunkeness where the fun has ceased and you begin to seriously regret your actions, while at the same time smiling, laughing and saying 'YOLO' with your friends, even though you know you really fucked up this time.
Dude 1: "Yo sup dude we gonna get shwacked tonight i got that absinthe"
Dude 2: "Man i cant wait hope i black out we gonna be belligerent"
Doctor: "You are both fucking retarded"
