depeditate
     
        /dee-ped'*-tayt/ [by (faulty) analogy with "decapitate"]
        Humorously, to cut off the feet of.  When one is using some
        computer-aided typesetting tools, careless placement of text
        blocks within a page or above a rule can result in chopped-off
        letter descenders.  Such letters are said to have been
        depeditated.
