Messageboard Lingo

Even though I'm not 100% new, I still don't know what all of the msgboard lingo is around here....so maybe some of you can help!

Maybe we can make a list of things and some of the veterans can help answer?

Here is what I know:

FH--future husband
MIL-Mother In Law
SIL-Sister In Law
BIL-Brother In Law
RH-Reception Hall

But what are these?

DH
BOK

DH - Darling/Dear/Dumb Husband
BoK - Bouquet

Ohhhh I didn't know that existed but looky there it is!!!

Oops!!!!!

Thanks!! :)
