Legal Terms for Everyday Use: The "12(b)(6)"

12(b)(6) - A situation where no matter what you do, you're not getting laid - usually time to abandon ship.

"Yeah, that girl's a total 12(b)(6). She's not leaving her friends tonight."

Source: Federal Rule of Civil Procedure 12(b)(6):

Every defense, in law or fact, to a claim for relief in any pleading, whether a claim, counterclaim, cross-claim, or third-party claim, shall be asserted in the responsive pleading thereto if one is required, except that the following defenses may at the option of the pleader be made by motion: ...
failure to state a claim upon which relief can be granted...

Basically, it's a motion that says "even if everything you said in your complaint is true, you're fucked because there's nothing the law can do for you." In other words, you're still not getting any action, no matter how good your game.
