RTFM: /R-T-F-M/ [UNIX] imp. Acronym for `Read The Fucking Manual'. 1. Used by gurus to brush off questions they consider trivial or annoying. Compare Don't do that, then! 2. Used when reporting a problem to indicate that you aren't just asking out of randomness. "No, I can't figure out how to interface UNIX to my toaster, and yes, I have RTFM." Unlike sense 1, this use is considered polite. See also RTFAQ, RTM. The variant RTFS, where S = `Standard', has also been reported. Compare UTSL.
