Either way, “Jakweenie” is the official designation for Jacob and Queenie, and ultimately that’s what’s more than likely going to stick.
Considering that “Jakweenie” is the Rowling approved name for Queenie and Jacob, one could assume that the previously submitted fan generated ship name was “Quakob.”
While it’s easier to say from a constructive standpoint, it sounds rather silly to say.
Adjust your Tumblr posts accordingly folks, these names are ironclad, from J.K. Rowling herself.
