__DATA__
Insult grammar by Micah Jaffe (zeade@cyclone.stanford.edu)
It creates three basic types with even more sub-types, etc etc.
Hehe.  Some of the adjectives and <noun_prep>'s were taken from
the Macintosh hypercard stack "Random Insults."  The curses are all
"original" ;)
------------------------------------------------------

{
<start>
You <adj> <name> . ;
May <curse> . ;

Some others you may want to include, but I like the other two better:

You are so <adj1> that even a <noun> would not want to <good_verb> you . ;
With the <force> of <metaphor> , may <curse> . ;

adj1 deals more with um degrading things about the person abilities,
adj2 more about appearance (used when refering to the mutant beasties)
