lossage
     
         /los'*j/ The result of a {bug} or malfunction.  This
        is a mass or collective noun.  "What a loss!" and "What
        lossage!"  are nearly synonymous.  The former is slightly more
        particular to the speaker's present circumstances; the latter
        implies a continuing {lose} of which the speaker is currently
        a victim.  Thus (for example) a temporary hardware failure is
        a loss, but bugs in an important tool (like a compiler) are
        serious lossage.
