I'm a fan of made up words. :) These are two of my favorites.
Ristupidiculous: when something is both stupid and ridiculous; saying this just make you feel a little more emphatic when trying to convey the idea that something is beyond ridiculous and stupid. Trust me.
Splendiferous: splendid and wonderous/wonderful. Again, another great word that just has that little extra 'umph' to it. Plays well with sarcasm.
