Used to describe being high. Specifically in public places where saying "I'm blazed" or "I'm so high right now" would be inappropriate. A great alternative to use with you and your buddies to know your state of mind.
"Dude I am so unbelievably skiid right now." (Lady working at Subway has no idea). "For real man? I'm a little skiid."
