A person's RFS can be used to distinguish the validity of a message commonly received through visual and auditory channels (televison, radio, third party interraction, etc.).
The RFS is also charged with determining what the person does with information they receive. If they choose to share the information as well as accompany it with an opinion, their audience will be placed in a position to determine if the messenger's RFS is working properly.
RFS, when used in the descriptive sense, is most often used when referring to a person who posts inaccurate information while passing it off as fact... then proceeds to vent, ramble, pontificate or lecture about their views on the subject matter without any realization of how they are perceived by the recipients of their postings.
Their opinionated message is most often followed by incessant postings over an extended period of time. So much so, that the recipients either ignore or simply block/unfriend the person in order to relieve themselves of the constant barrage of redonkulousness.
Butch: Yeah, he posts that stuff ALL THE TIME!!! Fred's RFS is so out of wack that he doesn't realize most of the folks on his friends list think he's absolutely nutz! That, or he simply likes being an inconsiderate crazyass.
The list of acronyms "grows by the month" and they are collected along with emoticons and smileys into folk dictionaries that are circulated informally amongst users of Usenet, IRC, and other forms of (textual) computer-mediated communication. These initialisms are controversial, and several authors recommend against their use, either in general or in specific contexts such as business communications.
On May 15, 2011, RFS was formally recognized in an update of the Urban Dictionary.
Guy 2: Whoa that's funny, RFS.
Dude 2: Why do you say that?
Dude: He doesn't even leave the house in case he gets a new notification.
