A conversation ender. Used at the end of a statement when a
person in the middle of a conversation wishes to stop talking about it immediately.
Coined from the TV
show LOST, where at the end of every episode, the
word "LOST" flashes across the screen, ending the episode very abruptly or on a cliffhanger.
Guy 1: "So I totally hooked up with that hot
blonde last night at the
party. I
wish I had gotten her number."
Guy 2: "Dude, that was my cousin. LOST."
