You know hip hop is completely played out when conservative columnist Pat Buchanan starts using hip hop slang. From his column on McCain's Mutiny:
For dissing his colleagues and Frist, and leaving Bush's Supreme Court nominees subject to a filibuster gauntlet and death by a thousand cuts, McCain is being hailed as the conscience of the Senate. But the ball is now back in the court of the majority, Frist and President Bush himself.
I thought I was misreading this at first, but no, there it was - the term "dissing" as plain as day. I'll grant that the word is old enough to be a daddy, but when the elderly start writing it in a column you know that hip hop is done.
