I got this from Shattered Empires all the wy back in 1999. Basically, I say a word, like -
"COW"
And you have to come up with what the letters stand for
"Computerized Office Worker"
Then, once you've done that, you give another world, like
"FIRE"
and someone else has to give an acryonym!
Okay! First word is...
WORLD
