The feeling you get the morning after getting extremely stoned the night before. Somewhat of a confused "not all there" feeling, as if you were still stoned but not.

Damn dude, we just smoked an O last night and I have afterburn.

I think I have afterburn, I got so stoned last night and I can't think straight.

This is a term I came up with when smoking pot.
