This term is reserved for supervisors who you as a subordinate brief your way out of a jam on an excel spreadsheet. This can be most conviently described as when you are giving a briefing of some sort, like on an excel spreadsheet. And when you explain or brief your way out of a problem. The supervisor or boss will just add an extra column and you then fucked again.
What the fuck man? I thought you had briefed your way out of that jam. Yeah me too until that asshat pulled out the add an extra column to the spreadsheet. Yeah I know he did pull out the ball bag musket on you.
Synonym for bonus points or extra credit; can be used as a verbal reward for a job well done. Usually does not involve actual cookies.
The term can be traced to the CW drama SUPERNATURAL: during a conversation between on-screen brothers Dean and Sam Winchester (played by Jensen Ackles and Jared Padalecki) Dean says "See that attitude right there? That's why I always got the extra cookie."
1. Great work! You get the extra cookie!
2. Can you read this and tell me if it makes sense? Extra cookies if you catch any misspellings!
