A social terrorist who has already been told to leave, but remains anyway.
To lose a primary election, but to end up running in the general election anyway as a third-party candidate, so as to spite the primary winner by trying to steal votes from him/her. See Charlie Crist.
I could have swore that I told that lame douchebag to leave my party since he was not invited. He's still here twenty minutes later, starting arguments with my best friends, and creeping out my lady friends. Is he trying to pull a Lisa Murkowski on me?
Since Daddy's Little Girl (a.k.a. Lisa Murkowski) lost the primary to hold on to her Senate seat inherited from her father, her sense of entitlement overrode her sense of decency (assuming she had any), and she decided to run as a third-party candidate in order to steal votes from Joe Miller, the man who beat her in the primary, out of spite.
