This is when you have had so much to drink, you literally cannot function in a social situation. Victims usually possess the knowledge that they have indeed drank way too much, but sometimes the situation is known only by your peers. The words "I'm so wasted" or "I shouldn't be here" frequent the victim. The next day, one will not remember anything or very little of what happened during the event.
Person 1: What happened last night?
Person 2: I don't remember man i was so weised it wasn't even funny.
Person 1: Did we have to put Stacey on a cab around 10?
