Good question! Well, it’s not a typo of an egg “yolk” it’s actually Dublin slang, a term used to describe something other than it’s proper name..
“You’re such a silly yoke!!!”
“Pass me that yoke, there, would you?”
“I need to grab some groceries and other yokes from the car!”
As you might have read on my “About Me” page, I’m from Dublin, Ireland and I am very patriotic about it- as is anyone about where they consider home. ?
I hope that helps, it’s a bit silly, but that’s me in a nutshell :)!
