In the intro of the video game, Zero Wing, one of the last comments says to "Move every Zig."
This has been adopted as "Let's move out" or "let's roll!"
"Guys, there's a sale at first and main! Move zig!"
A very, very bad thing to do. Most often, when a bad move is committed, many people are made very unhappy. Short of the rape, torture, and murder of the Pope's favorite Sunday school pupil, a Bad Move is the worst possible thing to do.
Subtracting from one side of an equation and not from the other, suggesting that someone go outside wearing a black belt with brown shoes, or trying to bribe the ravenous Bugblatter Beast of Traal out of swallowing you whole when you only have 12 Altairian dollars to give it. All of the above are sufficient Bad Moves.
A "dick move" is defined as being any action that requires an outstanding amount of courage and a remarkable lack of forethought.
You: BOOOYAAAA! I just did my girlfriend's sister.
Me: Dick move.
An action that gives one person an advantage while disadvantaging the other person/people involved and not feeling the least bit of remorse for it.
Commentator 1: "Did you see Dale Earnhart Jr. cut off Jeff Gordon and cause him to crash, taking the lead?"
Commentator 2: "That's what we call a jew move, Bill."
An action by a sports team to another sports team which violates understood social/sportsmanship expectations, especially where the transgressor obtains a slight advantage in comparison to the relatively large bounty placed on the transgressors future student athletes.
On Saturday October 27th, 2007 when the entire University of Georgia football team stormed the field in celebration of there first of many scores on the day, that was a dick move!
