High Definition Burn 

A condition that occurs after many hours of exposure to a High Definition Television. Similar to a sunburn, but caused by the clear and bright light emitted from a High Definition Television.

Last night, while watching a Blu-Ray copy of Troy on my HDTV, I came away with a High Definition burn.

"Dude, I watched Tenacious D and The Pick of Destiny last night...in high definition! My brain exploded to shit."

Wide Screen High Definition Wall 

America’s Iron Curtain, the wall of infotainment that prevents Americans from getting the information most important to their daily lives. The consolidated mainstream media eclipsing free speech with commercial speech.

Corporate greed and the Right Wing agenda have been served by confining America behind a Wide Screen High Definition Wall.
