SCUE (Jinx)

In Murphy's law terms, the SCUE is the thing that can and will go wrong. The most useless of underlings, the SCUE is the last person you want on your team. They cannot follow or understand instructions; they can find the best way to sabotage your efforts with the precision of an idiot savant. There is a good case for shooting thme on sight, but it is usually better to pay them to work for your competition. (Example: Toad).
