A slang term for pouring a drink into your mouth from the air, hence the term "sky". It is commonly done by teenagers who all want to share one drink without having to physically touch each other's saliva.
Also: skying, skyed
Examples (fictional people):
1: Markus asked his lad if he could sky some of his drink.
2: "Sorry mate, I've already skyed the rest of the cola to my best bud."
3: Skying drinks has become a new way of drinking for secondary school students.
A lethal combination of smarts and fire power. This cybernetic genius can do everything you can do and more. He's got his own re-loaders and can link with his base to generate units from opening, and, every time you beat Sky Captain he gets a little tougher.
