   loss
    n.
       Something (not a person) that loses; a situation in which something is
       losing. Emphatic forms include moby loss, and total loss, complete loss.
       Common interjections are “What a loss!” and “What a moby loss!” Note that
       moby loss is OK even though **moby loser is not used; applied to an
       abstract noun, moby is simply a magnifier, whereas when applied to a person
       it implies substance and has positive connotations. Compare lossage.
