just a thought....
you can also have the snippet on load put each list of drinks into it's own hash then do
something like this..
just another way to make it a tad bit shorter.

on *:text:!*:#:{
  if ($regex($1-,/( $+ $hget(Drink,Martini) $+ )/iS)) { describe # fixes $nick a $regml(1) Martini }
  elseif ($regex($1-,/( $+ $hget(Drink,Margarita) $+ )/iS)) { describe # blends up a $regml(1) Margarita for $nick }
}

and so on
