Tired and emotional is a chiefly British euphemism for being drunk. It was popularised by the British satirical magazine Private Eye in 1967 after being used in a spoof diplomatic memo to describe the state of Labour Cabinet minister George Brown, but is now used as a stock phrase, possibly because of British slander and libel law.
“In my view, we don’t have a two-party system. We have a one-party system: The Big Gov’t Party. It has a Republican wing that likes war and deficits and assault civil liberties, and it has a Democratic wing that likes welfare and taxes and assaults commercial liberties.”—Judge Andrew Napolitano (via stoge)
