I have a question about forum abbreviations. What do they stand for? There are many I have never seen before being on LPSG (we all know that one, lol) Please add the ones you know. LOL = Laugh out loud. LMAO = Laugh my arse off. BRB = Be right back. IMHO = In my honest opinion. WTF = What the Fuck. OMG = Oh my God. OMFG = Oh my fucking God.
