When someone who's been chatting in a chat room suddenly exits, due to hitting the exit button or similar by accident, and then enters only a few seconds after.

Originates from a time when WhiteRaven, a member at www.tuomas-holopainen.com, suddenly exited the Tuomas-chat on the page, and then entered only seconds later, several times on the same day, someday in December 2010. The term has been used by people in the chat room ever since.

Abbreviation: "Raven"
"Alex did a Raven fail, haha", "Sorry, I did a Raven" :p
