Person A: Why don't you talk about (game) in this chat?
Person B: Well, I am a fan of that game, but one of my friends has a really big anxiety trigger involving it, so I don't mention it out of respect.

A phenomenon that occurs when a cat is startled, typically as a result of something completely insignificant, setting off other nearby cats in a cat-dense area, causing a positive feedback loop of mayhem. In particular, nearby fragile objects on top of furniture, and in some cases the furniture itself, are likely to be damaged or destroyed in such an event.

Lost "nuked the hatch" - "sunk the island"
TV terms to describe a moment when something that was once great has reached a point where the finale changed how you viewed the show.
The origin of this phrase comes from a Lost episode where the cast of Lost nuked the hatch and sunk the island and ended the show in purgatory.
Thus was labeled the lowest point of the show... May 23rd, 2010

Guy 2: Where?
Guy: Right there! Don't you hear the siren...
*BIG EXPLOSION*
