A Branditard is a noun referring to mostly middle aged female fans of reality star Brandi Glanville who are lonely and do not have any lives of their own, and they mostly rabidly follow her on twitter. They are obsessed with her tweets, and they worship her and hang on to her every word. They attack anyone who does not agree with Brandi Glanville. They mostly loathe LeAnn Rimes and attack her any change that can get. Therefore, they are referred to as "Brandtards".
Branditards usually scream "Team Brandi". That is their motto.
