Rtfm
Appearance
RTFM means Read The Fucking Manual. This is a typical reply to a question that is "n00bish". So if you ask someone a question about for example how to do something in a certain program, you might expect a "RTFM!" in reply.
Example:
<Trulz>: [charzer], how do I edit my email-settings in Opera?
<[charzer]>: hmm...let's see....RTFM!!!
