Another term for awesome, cool, uber sweet, totally legit, and just plain out sick nasty. Invented in 2010 in a coffee shop in rural Roanoke, Virginia, it is possibly the most effective word ever used. Not only is shwangadoo a cleverly usable adjective, it can be used in many situations.
To be shanged is to be extremely high. It is acceptable to use this term when you are having hallucinations or are feeling the beginning stages of an orgasm with no sexual stimulation. It's a good thing to be; a very good thing to be.
