Shwangtown is derived from the word "shwang". It's state of mind - whether you're looking to have a chill time, hang out with your friends, or the vibe is good.
"You guys down to go to shwangtown tonight?"
"Yeah, I'll come over at eight".

Another term for awesome, cool, ubersweet, 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...
