:RTFM

{{Short description|Initialism for "read the fucking manual"}}

{{Other uses}}RTFM is an initialism and internet slang for the expression "read the fucking manual", typically used to reply to a basic question where the answer is easily found in the documentation, user guide, owner's manual, man page, online help, internet forum, software documentation or FAQ.

Usage is variously viewed as a pointed reminder of etiquette to try to find a solution before posting to a mass forum or email alias;{{cite web |url=https://www.sqlskills.com/blogs/paul/rtfm-no-seriously-r-t-f-m-then-ask-your-question/ |title=RTFM.

In expurgated texts, substitutions such as "read the frickn' manual", "read the factory manual", "read the field manual", "read the flaming manual", "read the fine manual", "read the friendly manual", "read the [pause] manual" or similar variants are used.Howard, Michael, David LeBlanc, and John Viega. 19 Deadly Sins of Software Security: Programming Flaws and How to Fix Them.

If there is no appropriate content in the manual but the answer is frequently seen in the forum, a similar response in internet culture might be to "lurk moar", meaning to observe the forum for a time before asking questions.

A related phrase is "let me Google that for you" (LMGTFY). In this case, the "manual" is the World Wide Web, so one of several search engines such as Google could be used to look up the answer. In many cases, doing so provides an answer in less time than it takes to ask someone else the question. The range of usage is similar to that for RTFM.{{cite web |url=https://metatalk.metafilter.com/13526/Let-me-google-that-for-you |title=Let me google that for you |date=22 January 2007 |access-date=2023-09-17}}
