A common disease amongst fanfiction writers, affects your ability to write a fic beyond the first chapter. The writer is never satisfied with the first chapter of his/her fic and thus can not finish said fic.
Due to Mary-Sue's first chapter syndrome, she was not able to finish the fanfic she was writing in time for the contest deadline.
Much like a Blanket Monster a Shower Monster is any of the following:
a. A person who is constantly showering
b. A person who uses up all the hot water and leaves others to freeze
c. A person who takes an excessively long time in the shower (A.K.A. Bathroom Monster)
A. Since Bill was a germaphobe he was constantly taking showers, this earned him the nick name 'The Shower Monster.'
B. When Cindy was at camp it seemed as if you was always preceded by a Shower Monster. Not once her entire time there did she get a hot shower.
C. Jose's older sister was such a Shower Monster that often times she didn't leave the bathroom until after breakfast.
