You are so fucked up that you have no control over your your sensory or motor functions. You can't even speak, only noises are muttered. You walk out of the bar looking like you just got kicked in the face by a donkey. The highest degree of drunkeness possible.
"Man last night I was donkey shlankled off my ass and banged a 400 lb black chick. I have never been that fucked up before."
"Are you going to the bar tonight."
Response: "Hell yeah man I'm gettin Donkey Shlankled wasted."
