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.
He's the guy who enjoys dressing in Granny's p.j.'s (is sometimes seen wearing a bright silver cape), has ears so large he can use them as weapons in battle, breath that smells like rotting snail slime and eats the cheese fugus between his own toes.
Warning! Stay as far away from this character as possible!! He has a horrible aim and so he'll try to freak you out by posing like a muscle man but ends up looking like a constipated turtle with extremely large ears.
