A game from the 1982 movie TRON. Encom recently remastered the game and uploaded it to the interwebs for everyone to play. Currently, the only person to reach the top score of Space Paranoids is Kevin Flynn, with a score of 999,000. The player drives a tank and tries to shoot down turrets, other tanks, and flying ship things called Recognizers.

A lighthearted reaction upon receiving disappointing news of some sort. Usually something that isn't a particularly a big deal, esp. when it primarily affects someone else - sort of a mild schadenfreude. Sometimes doubled or tripled, and possibly said in a sing-songy voice for added comedic effect to imitate a muted trumpet, which is how the meme originated.
