Stycious: What it means is basically cool or fly in a very laid back kind of way. You use the word when your completely relaxed and you just found out a good bit of news. OR, you can use it as a compliment even.

It's basically another way of saying "cool" or "fly" in a very laid back kind of way. It can also be used as a compliment. This is not a word that should be shouted with excitement... its very relaxed and calm.
