This is simple and fun - I found it on another forum. I'll start by posting a random combination of letters which is an abbreviation for something. You have to guess what it stands for. Then post your own set of random letters for the next poster to guess.
IMPORTANT NOTE: the abbreviation doesn't have to be real - in fact it's more fun if you avoid any real ones. For instance if someone posts BTW, don't go for By the Way, but make something up, e.g. Bread Tastes Wonderful.
Keep it clean and in good taste!
So to start:
