Jackalaka
A person who is totally awesome in the south of England but is a brainless idiot in the north, Wales, and Scotland. In Ireland, it’s just a fancy way to say beer.
"You’re a jackalaka!" he said, while I was just trying to survive the train ride to Manchester.
"I’m a jackalaka," she said, while I was being called a jackalaka by three different people.
He drank a whole pint of beer and said, "This is a jackalaka."
