  Lobster \Lob"ster\, n. [AS. loppestre, lopystre prob., corrupted
     fr. L. locusta a marine shellfish, a kind of lobster, a
     locust. Cf. {Locust}.] (Zool.)
     1. Any large macrurous crustacean used as food, esp. those of
        the genus {Homarus}; as the American lobster ({Homarus
        Americanus}), and the European lobster ({Homarus


        vulgaris}). The Norwegian lobster ({Nephrops Norvegicus})
        is similar in form. All these have a pair of large unequal
        claws. The spiny lobsters of more southern waters,
        belonging to {Palinurus}, {Panulirus}, and allied genera,
        have no large claws. The fresh-water crayfishes are
        sometimes called lobsters.
        [1913 Webster]
  
     2. As a term of opprobrium or contempt: A gullible, awkward,
        bungling, or undesirable person. [Slang]
        [Webster 1913 Suppl.]
  
     {Lobster caterpillar} (Zool.), the caterpillar of a European
        bombycid moth ({Stauropus fagi}); -- so called from its
        form.
  
     {Lobster louse} (Zool.), a copepod crustacean ({Nicotho["e]
        astaci}) parasitic on the gills of the European lobster.
        [1913 Webster]
