When comments or wall posts left on a friend's Facebook profile, posts, or pictures are later deleted, either 1) by the owner of the profile or 2) by the person who originated the post.
1) Occurs most frequently when comments are unflattering or incriminating. Also can be necessary to delete over posts left by the person you're casually banging, in attempt to lay claim on your or salt your game.
A more up-to-date way to annoy friends on social networking sites. A "new rick roll" becomes especially necessary when no one even checks the links you post anymore, because you've already rick rolled all your friends multiple times.
Specific examples of the new rick roll can include but are not limited too: running a straight like on someone's page or pulling a status highjack.
Mike: What are you giggling about?
Sally: I just straight liked five people, its my new rick roll.
