Adjective: Condition of a person after 1) finding out an act of vandalism has been committed to their property, 2) accusing their hated rival of being responsible, and then 3) finding out it was one of their own who actually did it.
When someone broke off a piece of Clemson's famed "Howard's Rock" Clemson fans spent a week accusing USC and UGA fans of being responsible. When the news came out that it was actually one of their own fans who was arrested for the crime, it was very "Clembarassing"
