But after some research, National Geographic has confirmed that the pop star was referring to this incredible shot of the Royal's legend, George Brett, surrounded by a flock of baseball-holding fans:
In an interview a few months ago with VH1, Lorde (real name Ella Yelich-O’Connor) explained how she "had this image from the National Geographic of this dude just signing baseballs. He was a baseball player and his shirt said, 'Royals.'"
"It was just that word. It’s really cool."
The music world is just thankful the young songbird wasn't around to remember this image of Brett from the Pine Tar Incident:
