A time in which one is too a. Drunk and b. Drugged that neither word is worthy of the explanation of the state in which one is in. Boonswaggled is basically derived from acting like a crazy goon or baboon and makeing noises while wabbling ones body since their state is so uncontrolably drunk/drugged. People tend to make complete asses of themselves at this state and blaming it on the large amounts of drugs and alcohol done that night.
"Dude, I was soo boonswaggled last night I drank piss out of the spit bucket and ran around naked until I forgot where the house party was at..."
