Literally "Read The F**king Manual"; a term showing the frustration of being bothered with questions so trivial that the asker could have quickly figured out the answer on their own with minimal effort, usually by reading readily-available documents. People who say "RTFM!" might be considered rude, but the true rude ones are the annoying people who take absolutely no self-responibility and expect to have all the answers handed to them personally.
"Damn, that's the twelveth time that somebody posted this question to the messageboard today! RTFM, already!"

Proponents of such acronyms encouraging new users to look the information up themselves are often discouraging questions that could easily be answered using the FAQs, Wiki or Google.

RTFM frequents questions that common sense should have precluded asking.

Some may choose to reply in this fashion rather than leaving the newbie without a response so as to clarify what types of questions are considered inappropriate, unintelligent or inconsiderate of others' time.

originally: "read the field manual" used by WWII soldiers when asked basic questions by new enlistees.

rtfm quickly spread to engineering, computer & technical fields, and has gained popularity with internet usage.

its applicability has increased dramatically with the advent of wiki, where the answer is already at everyone's fingertips.
then:

rookie: how am i supposed to clean this m1?
veteran: read the field manual.

now:

noob: how do i install linux?
1337: rtfm @ linux.org/docs/beginner/install.html

polite usage that will increase likelihood of a helpful response:

newbie: how do i...? i have already rtfm.

murderhobo 

In a tabletop game, a murderhobo is a player who murders NPCs indiscriminately. This is normally derogatory, referring to a player who totally ignores quests, dialog, backstory, trade, world building etc.

The term is most common with Dungeons and Dragons, but it can be applied to most RPGs where the player is allowed to kill most quest-giving NPCs and NPC traders. E.g. Elder Scrolls, Fallout, Divinity original sin.

In sales terms, a whale is a prospect that is significantly larger than an organization’s average customer.

Whales are large and extremely difficult to close. Due to their immense size, they are highly sought-after.

A whale is typically identified at first by a whale hunter on the sales team, but often requires cross-discipline participation in order to close; this includes assistance from operations, engineering, creative, client success, and business development teams.
"Shit...the sales director chewed me out on the sales call this morning. He's totally pissed that I have nothing in my pipeline. I've been focused on this one whale for so long that I haven't had time to prospect for normal-sized deals."
