Not trivial since many checks are used to sidetrack email these days, 
some of which are difficult to bypass. For example if you are blocking 
using spamhaus at the MTA level you'll never even see the subject. What 
About viruses. Does the user want a virus or a message with a blocked 
attachment if the subject has the magic word.

You get the idea.

On a simple level you could write a series of SpamAssassin rules that 
would add +100 to the score if the magic words appear in the subject but 
this only covers part of the possible traps.
