The act of falling asleep on the toilet, generally after consuming a large quantity of alcohol. Sitting on it nude and clasping a book is optional.
"I couln't get into the toilet last night. Chris had come home pissed and performed a 'Half Elvis'. It took 30 minutes of banging on the door until he woke up!"
