I just want to help out fellow lurkers and newbies/am a little slow to pick up on things sometimes. In addition to all the widely known wedding acronyms (MOB, MOG, FOB, FOG, MOH, FMIL, FFIL, FSIL, STDs, etc.), there are some that I've seen that are exclusive to the Knot, like
PPD: "Pretty Princess Day"
SS: "Special Snowflakes" (before I figured this one out, I thought this was a Godwin's Law situation and all the bridezillas were being called Nazis)
DW: "Destination Wedding"
WW: "Wedding Wire" (usually used in the context of "WW troll")
Still stuck on "SITB", "AHR," and a few others. Searching the boards doesn't really help.
Re: The Knot Acronyms
SITB - stuck in the box (when the quote boxes aren't working correctly)
AHR - at home reception
SITB= Stuck in the box
AHR= at home reception
STIB = Stuck in Box
AHR = At Home Reception
One of the boards has a sticky with this I think, it might not have them all though
Also, sometimes I use these in texts with friends and it completely confuses them but I struggle to switch out of Knot mode.
AW= Attention Whore
DD= Dirty Delete. Deleting a thread after posting it is consider poor form.
FTFY= Fixed that for you.
I am trying to think of which ones I struggled with when I first started posting.
Here's a pretty thorough discussion on the acronyms
