Dave Matthews Band Syndrome (D.M.B.S.) is a negative characteristic of something, which is otherwise enjoyable, but you are forced to HATE because said something's fans lack the ability to shut the fuck up about how much they love it.
My Little Pony: Friendship is Magic suffers from Dave Matthews Band Syndrome. See also The New York Yankees, Metallica, and Harry Potter.
