Now, I don't want to go on a rant here, but America's foreign policy makes about as much sense as Beowulf having sex with Robert Fulton at the first battle of Antietam. I mean, when a neo-conservative defenestrates, it's like Raskolnikov filibuster deoxymonohydroxinate.

Peter

What the hell does "rant" mean?
