As a long time reader and newish poster, I've come across some acronyms we use here that I haven't come across anywhere else. Maybe this thread can help fill in the blanks for me and other new posters?
FYSMC = f*** you, suck my cock
TLDR = Too long, didn't read
CHP = ???
Also can anyone explain the origins of "dumn"?
Please add to this list, going off the top of my head here.
