The act of abruptly leaving a social function with
little to no notification because you have decided
you are tired, bored, or "just done". There are no lingering farewells, and oftentimes it is done so quickly
that (like a flash) others are unaware that you have even left.
Partygoer 1: "Hey, where is Jackie?"
Partygoer 2: "Oh, you know how she likes to white
out. She's been gone for thirty
minutes or more...just decided she was done
with this party!"
