'r 

suffix added to the end of a verb or other type of word to transform it into a noun, as one ‘doing’ the verb, sometimes not taken entirely literally; equivalent to tagging on an ‘-er’{hyphen included}, though consumes less space and takes less time to type, plus looks cleaner for ‘irregular’ and acronymic verbs which may not stand as a verb when alone, though when an ‘'r’ becomes its ending it takes on a somewhat colloquial meaning.

By my book\In my eyes, Pete Rose *is* an MBL HoF'r, even if he doesn’t have his name on a plaque declaring such.

{Translation: As I see it, P. Rose *is* in the Major-League Baseball Hall of Fame, even if he doeesn’t hold the honor of having his name embedded on a plaque declaring such, or he damn-well deserves to be at any rate.}

r/ means Reddit/ but it can be seen on other platforms such as Youtube, Twitter, Instagram etc. etc. and people say r/woooosh or r/foundthemobileuser or even r/cursedcomments it goes on and on and on it never stops the possibilities are actually endless. It is very interesting to think about and I think it is great!

Jack: Emily what is the name of the subreddit that posts memes?

Jack: If you call me an idiot again I'm telling mom!

Emily: Idiot.
