n, A low brow British person who hates Americans and can't argue with one without bringing up the American Revolution, and calling them a Yank as an insult. Similar to an American from the south who hates Northerners and can't argue with one without bringing up the Civil War (the War of Northern Aggression), and calling them a Yankee as an insult. Derived from combination of red coat and red neck.
Do you hear that red coat neck arguing with that Southern hick? If he calls him a Yank, somebody is going to end up in the hospital! ... let's watch.
