The act of searching someone's Facebook photos for a really old picture from years ago. Specifically for a funny or embarrassing picture and then liking it so that it magically appears back on the news feed for all of that person's friends to see. Invented by Mike Keegan and Charlie Blakeman.
John: "Man I thought that picture of me with the hooker from 5 years ago was long lost until those idiots Mike and Charlie TIME BOMBED me and now its all over Facebook again!"
