look up any word, like fellated:
 
1.
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.
Example: Dude, those new shoes you bought are so shwangadoo!

Did you watch that video about the guy who stabbed that kitten? I wish i was that shwangadoo...
