Oooookay, to steer us away from careful examination of ways to represent the male (and probably female, eventually) genitalia in ASCII, I propose that we examine some more obscure, DWAAARF FORTRESS related abbreviations.
For instance:
HFS - Hidden Fun Stuff, meaning the... *SPOILER ALERT* PLEASE LOOK AWAY NOW IF YOU DON'T WANT THE ONE LAST REFUGE OF DWAAARF FORTRESS OBSCURITY REVEALED BEFORE YOUR VIRGIN EYES
... very rare pit located deep within certain mountain tiles that contains, among other things... *SPOILER ALERT* I REALLY MEAN IT THIS TIME. IF YOU GO ANY FURTHER YOU'RE JUST ASKING FOR THIS GAME'S ONE SECRET TO BE MADE CLEAR AND SEVERELY UN-FUN.
... a number of quite deadly demons, some magma (if I remember correctly)... *SPOILER ALERT* ALRIGHT. I AM SERIOUSLY SERIOUS NOW. IF YOU DO NOT AVERT YOUR EYES THIS VERY INSTANT THE SHEER MAGNITUDE OF WHAT SHALL BE REVEALED UNTO YOU MAY CAUSE YOUR HEAD TO EXPLODE. DON'T SAY I DIDN'T WARN YOU.
YOU'RE GOING TO SAY IT, AREN'T YOU? WELL, DON'T! I ALREADY EXPLAINED ONCE. GOODNESS. SOME PEOPLE...
... and a number of engravings of various animals and people engaged in "depraved acts."
SEEEEEEE? I TOLD YOU IT WOULD RUIN IT. ARE YOU HAPPY WITH YOURSELF?
I THOUGHT NOT.
...Oh, and there's some rather valuable adamantine as well.
OH FOR F**K'S SAKE YOU JUST HAD TO GO AND RUIN THE WHOLE THING FOR THEM, DIDN'T YOU? JEEZUS, WHAT IS YOU PEOPLES PROBLEM? YOU JUST HAVE TO KEEP PUSHING AND PUSHING, DON'T'CHA?
