The name of a popular television program on the ABC channel in early 2005. Follows a group of people who survived a plane crash while flying on an Oceanic Airlines flight from Sydney, Australia to Los Angeles. They try to survive on the island and encounter lots of odd things, including an invisible monster that may be able to communicate with the survivors, polar bears, a crazy woman who was part of a resarch team that was slaughtered on the island, a mysterious "black rock", strange voices, and more. The survivors also have to deal with problems faced within their camp, including the well-being of a woman who is pregnant, the hidden motives of a man named John Locke, and the communication barrer that exists between the survivors and a Korean couple who can't speak English. The show currently airs Wednesday at 9:00 EST on the ABC network.
John Locke: "You see this little hole? This moth's just about to emerge. It's in there right now, sturggling. It's digging it's way through the thick hide of the cocoon. Now, I could help it - take my knife, gently widen the opening, and the moth would be free - but it would be too weak to survive. Struggle is nature's way of strengthening it."

Word of the Day on October 28, 2026
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.
