Though the name of this form makes me think of liposuction and Tyler Durden's soap (ewww!), I tried it out anyway, as instructed, explicitly refraining from using a particular letter. Some lipogram poets ditch whole sections of the alphabet -- all vowels except one, for instance, or everything from K to P, or all the letters in a name. Rookie that I am, I just eliminated one little vowel. The letter I chose to strike from the roster was "i".
