This is a room in everybody's house where they keep the door closed because this is where they put all their junk that they don't know what else to do with it. So when you open the door the only thing you can say is "Oh My God".
Friend#1:What's behind that door?
Friend#2:Oh that's my OMG room.
Friend#1:Well let's have a look.
Friend#1:Oh My God!
