Foreground obstruction crew 

People and vehicles at airshows and airports charged with the vitally important task of obstructing photographers trying to get pictures of the aircraft. They typically wear orange shirts and/or reflective vests to enhance their visibility. They are best known for making their appearance *just* when the most interesting aircraft of the entire event is about to pass by, remaining present until they have spoiled the photo opportunity, and then returning to their lair.

Sh*t! My photo of that F-100 was spoiled by the foreground obstruction crew!

Forcedown 

When a particular subject becomes too much of a hassle for you to bear any longer. Usually used when one is upset about how what was once enjoyable has become too much to deal with.

This whole NCAA bracket thing has become a major Forcedown.

forecon 

A member of the United States Marine Force Reconnaissance or any other Special Forces Soldier or Elite Infantryman partaking in stealth or reconnaissance operations from anywhere in the world.

Naval officer: You will be working with a Elite British Forecons on this operation.
SEAL: The British don't have a Force Recon regiment.
Naval officer: No, they are PARAS and SAS men with extensive training. But we call them Forecons because it's easier.

Forefrontal 

To be long stanced, in one's face, or quite bare in one's attitude to another.

(In a heated discussion), I apologise for being so forefrontal
